Figures A and B are each made up of 3 identical rectangles. Both figures have the same area of 726 m
2 each. What is the perimeter of Figure B?
Area of one rectangle
= 726 ÷ 3
= 242 m2
Length of each rectangle = 2 Breadths of each rectangle.
Cut each rectangle into 2 squares.
Area of each square
= 242 ÷ 2
= 121 cm2
Breadth
= √121
= 11 m
Length
= 11 x 2
= 22 m
Perimeter of Figure B
= 4 x 22 + 6 x 11
= 154 m
Answer(s): 154 m
