Figures A and B are each made up of 3 identical rectangles. Both figures have the same area of 600 m
2 each. What is the perimeter of Figure B?
Area of one rectangle
= 600 ÷ 3
= 200 m2
Length of each rectangle = 2 Breadths of each rectangle.
Cut each rectangle into 2 squares.
Area of each square
= 200 ÷ 2
= 100 cm2
Breadth
= √100
= 10 m
Length
= 10 x 2
= 20 m
Perimeter of Figure B
= 4 x 20 + 6 x 10
= 140 m
Answer(s): 140 m
