Question

The area of rectangle field is 1600 sq m . If the length of the field is 80 m . Find the perimeter of the field.

Answer 1

Area of rectangle:L×B=1600m^2
80B=1600
B=20m
Perimeter=2(l+b)
= 2(80+20)
=2(100)
=200m

Answer 2

Dear Student,

◆ Answer -

Perimeter = 200 m

● Explanation -

# Given -

A = 1600 sq.m

l = 80 m

# Solution -

Area of the rectangle is calculated by -

A = l × b

Rearranging,

b = A / l

b = 1600 / 80

b = 20 m

Perimeter of the rectangle is -

P = 2 (l + b)

P = 2 (80 + 20)

P = 2 × 100

P = 200 m

Hence, perimeter of the rectangular field is 200 m.

Thanks dear. Hope this helps you..
