Question

If the perimeter of a field is 28 m and its breadth is 4 m, find its length.​

Answer 1

Answer:

10 m

Step-by-step explanation

perimeter= 28 m

breath= 4 m

length= x

          = 2(x+4)=28

          =(x+4)=28/2

          =(x+4)=14

          =x       =14-4

          = x       =10

Answer 2

Question

If the perimeter of a field is 28 m and its breadth is 4 m, find its length.

Solution

Given,

Perimeter of a rectangular field = 28m

Breadth of a rectangular field = 4m

Let the Length of a rectangular field = L

We have,

Perimeter of a rectangle = 28

=> 2(L+B) = 28

=> 2(L+4) = 28

=> 2L + 8 = 28

=> 2L = 28 - 8

=> L = 20/2

=> L = 10

Therefore the length of the rectangle is 10m
