Question

The area of a rectangle 20 m long is 240 m2. It’s perimeter is
m.

Answer 1

length of the rectangle = 20 m

area of the rectangle = 240 m^2

so ; breadth of the rectangle = 240/20 = 12

so perimeter will be equal to = 2 ( l+ b)

= 2 × 32

= 64 m ans..

Answer 2

Answer:

area of a rectangle = L×B

given L is 20m and area is 240m^2

20×B=240

B=240÷20

B=12

Now, perimeter of the rectangle is 2 (L+B)

=2 (20+12)

=2 (32)

=64 M
