Question

The perimeter of a rectangle is 8 dam and the difference between the length
and the breadth is 4 m. Find its area.​

Answer 1

Answer:

Let,

the length of the rectangle is = x m.

then, the breadth will be = (x-4) m.

the perimeter is = 8 dam or 80 m.

according to the question,

2* (x+x-4) = 80

2* (2x - 4) = 80

4x - 8 = 80

4x = 80+8

X = 88/4

= 22

the length is = 22 m.

the breadth is = (22-4) = 18 m.

the area of the rectangle is = (L*B)

= (22*18) m²

= 396 m²

ans: the area of the rectangle is 396 m².
