Answer 1

Given :

Area of rectangular field is 2100sq.m

Field is 60m long.

To Find :

It's perimeter = ?!

⇉ Solution :

↪$area \: = length \: \times breadth \\ ⇢breadth = \frac{area}{length \: } \\ b = \frac{2100}{60} \\ = 35m \\ \\ ↬perimeter \: = 2(l + b) \\ = 2(60 + 35) \\ = 190m.$

Answer 2

area=2100

l=60m

b=?

perimeter=?

area=l×b

b=area÷l

=2100÷60

b=35m

perimeter=2(l+b)

=2(60+35)

=2(95)

=190m
