Question

find the length of the rectangular field whose perimeter is 90meter and breadth is 20 meter

Answer 1

Solution:

Let Length = l

Breadth = 20 m

Perimeter of a rectangle = 2(l+b)

90 = 2(l+20)

45 = l+20

I = 25 m

Length is 25m

Answer 2

The length of the rectangular field is 25 m

Step-by-step explanation:

Let the length of rectangular field be x

Breadth of rectangular field = 20 m

Perimeter of rectangular field = $2(l+b)=2(x+20)$

We are given that perimeter is 90 meter

So,$2(x+20)= 90$

$x+20=45$

$x=25$

Hence the length of the rectangular field is 25 m
