The figure below is made up of 2 identical rectangles and two squares,A and B.
The perimeter of each rectangle is 44 cm. Find the area of the figure.
It is an attachment.

Hi,
Solution as follows:
Perimeter of each rectangle = 44cm
2 Lengths + 2 breadths = 44 cm
1 Length + 1 breadth = 44 divided by 2 = 22 cm (L = 18, B = 4 or L = 16, B= 6 or L = 15, B = 7. L + B should add up to sum of 22.. it does not matter, because the total area of the figure will be the same)
Let's take L = 18, and B = 4 (write this onto your diagram and you can see each side of the big square (the whole figure) = 18+22 cm
Area of the figure = (18+4) x (18+4) cm2 = 22x22 cm2 = 484 cm2
Ans: 484 cm2
