Answer 1

Answer:

required breadth of the rectangle is 10 m

Step-by-step explanation:

Length of rectangle is 40 m

Let breadth of the rectangle is a m

then area of the rectangle is (40×a) m^2 = 40a m^2

Now the side of a square is 20 m

then area of the square is (20)^2 = 400 m^2

according to question ,

area of the rectangle = area of the square

⇒ 40a = 400

⇒ a = 400/40

⇒ a = 10

Hence breadth of the rectangle is 10 m
