Figures A and B are each made up of 3 identical rectangles. Both figures have the same area of 294 m
2 each. What is the perimeter of Figure B?
Area of one rectangle
= 294 ÷ 3
= 98 m2
Length of each rectangle = 2 Breadths of each rectangle.
Cut each rectangle into 2 squares.
Area of each square
= 98 ÷ 2
= 49 cm2
Breadth
= √49
= 7 m
Length
= 7 x 2
= 14 m
Perimeter of Figure B
= 4 x 14 + 6 x 7
= 98 m
Answer(s): 98 m
