Figures A and B are each made up of 3 identical rectangles. Both figures have the same area of 384 m
2 each. What is the perimeter of Figure B?
Area of one rectangle
= 384 ÷ 3
= 128 m2
Length of each rectangle = 2 Breadths of each rectangle.
Cut each rectangle into 2 squares.
Area of each square
= 128 ÷ 2
= 64 cm2
Breadth
= √64
= 8 m
Length
= 8 x 2
= 16 m
Perimeter of Figure B
= 4 x 16 + 6 x 8
= 112 m
Answer(s): 112 m
