Question

a rectangular plot and a square plot have the same perimeter. the length of the rectangle is 20 cm and the breadth is 16 cm. find the area of the square.​

Answer 1

Explanation:

Given that,

The length of the rectangle is 20 cm and the breadth is 16 cm.

So,

The perimeter will be {2(20+16)}=72cm

As the rectangular plot and the square plot have the same perimeter.

Then,

The perimeter of the square is 72cm

We know,

The perimeter of a square is 4a

So,

The length of the square is (72/4)=18cm

Now,

The area of the square is (18cm)^2=324cm^2
