Question

The length of a rectangular field exceeds its breadth by 10m. If the perimeter of the field is
100m, find the length and breadth of the field.

Answer 1

Answer:

Breadth = 20

Lenght   = 30

Step-by-step explanation:

Breadth = x

Lenght = x + 10

Perimeter = 2(l+b)

                   2(x + x + 10)

                   2(2x + 10)

                   4x + 20

Now,

100 = 4x + 20

80 = 4x

20 = x

So Breadth = 20

     Lenght  = 20 + 10 = 30
