Answer:
128cm²
Step-by-step explanation:
Let the longer side of the rectangle be its length and the shorter side be its breadth as shown in the attached image.
We are given that the 3 rectangles are identical.
Also, if you see closely, you will realize that the sum of the breadth of the two rectangle is equal to the length of the rectangle.
∴ l = 2b-----(1)
The perimeter of the figure is 80cm.
A/q
l + b + l + b + b + l + b = 80cm ------ (2)
From (1) and (2), we get
=> 2b +b + 2b + b + b + 2b + b = 80cm
=> 10b=80
=> b=8cm
From (1)
l=2b
l = 8cm x 2 = 16cm
Area of a rectangle = l x b
= 16cm x 8cm
= 128cm²
