#Different shapes with the same perimeter worksheets how to#

Since the puppy will need to run and play in your backyard, we will need to build a fence around your backyard. This problem gives students plenty of opportunity to practise manipulating algebraic expressions within a purposeful context.Imagine you just got a puppy for your birthday. Along the way, the challenges will provoke some insights that will be worth sharing. The worksheet is also available in French: Expressions de pÃ©rimÃ¨tres This printable worksheet may be useful: Perimeter Expressions.pdf Issues relating to the dimensions in formulae for areas and lengths might emerge. Problem 1 : Find the area of the square shown below. We are grateful to Clara Huizink for translating the original. Problem 2 : Find the perimeter of the rectangle shown below. Hand out sheets of paper (A4 is ideal) and introduce the problem, giving students time to cut out their five rectangles. Show the image of Charlie's shape and ask students to work out the perimeter in terms of $a$ and $b$. The area of the smallest rectangle could be designated $R$ and used as a unit to express other areas, if students are not confident enough in their algebra to express it in terms of $a$ and $b$. Index of our basic and advanced-level fraction worksheets. Framework examples page 123 Sheets Worksheets 17 and 19 (Teacher Resource Pack) Homework. Once everyone is happy that the area is $9R$ or $9ab$ and the perimeter is $10a + 4b$, ask them to combine the largest and smallest rectangles (edge to edge, corner to corner) to make other shapes, and work out the areas and perimeters. Learn area, perimeter, symmetry, polygons, solid shapes, and more. Link to Area and Perimeter: Exercise 12 questions 3 and 8f. How many different perimeters can they find? So, the perimeter of the rectangle is 36 inches. Problem 2 : The perimeter of a rectangle is 42 cm. If its width is 3 more than twice its length, then find its length and with. Once they have done this, discuss: are they surprised that they only found one other possible perimeter, and that the two answers could be reached in several different ways? Solution: Let x be the length of the rectangle. The next challenge is to make different shapes using at least two of the rectangles, and again work out the area and perimeter. Students could make a shape in pairs and work out the area and perimeter to give to another pair (without letting them see the shape), to see if they can create a shape with the same area and perimeter. There is opportunity for fruitful discussion when the two Learn to find area of different shapes like circle, square, rectange, parallelogram and triangle with math area worksheets for kids.

#Expressions representing perimeter and area worksheets how to#Īfter students have learned how to find the area of different shapes then they can practice these mixed problems of finding areas. Different units of length are used in the problems so that students also learn. Shapes are compared, to see what is the same and what is different, and to see if one can be transformed into the other.Īlternatively, collect together the areas and perimeters on the board. Then in pairs, challenge students to combine rectangles to make each of the area/perimeter combinations listed on the board, checking each other's work as they go along.įinally, the 'questions to consider' provide some interesting points for discussion - students could be invited to suggest questions they think mathematicians might ask themselves, with the list in the problem used to prompt ideas if necessary. #Expressions representing perimeter and area worksheets how to#.
