Question

if the perimeter of a rectangle is 1600 m and breadth is 20 m . find the length of the rectangle​

Answer 1

Step-by-step explanation:

The perimeter of rectangle = 1600

l x b= 1600

l x 20 = 1600

l= 1600/20

l = 80 cm

Answer 2

Step-by-step explanation:

A=1600

L=20

Solution

Area of the rectangle is calculated by

A=l× b

Rearranging,

b= A/ l

b= 1600/20

b= 80

Perimeter of the rectangle is

p=2(l+b)

p=2(20+80)

p= 2×100

p= 200

Hence perimeter of the rectangle field is 200 m.
