Question

what will be the area of field if the perimeter of rectangular fiekd is 480 m and the ratio of its adjacent sides is 5,3 ?

Answer 1

Given: Perimeter is 480m and ratio of their adjacent sides are 5x and 3x.

To find: The area of the field.

Answer:

Let us take the length as 5x and the breadth to be 3x.

Formula to find perimeter: Perimeter = 2(l + b).

Substituting the given values,

480m = 2(5x + 3x)

480m = 2*8x

480m = 16x

x = 480/16

x = 30

Therefore length = 5x = 5*30 = 150m and breadth = 3x = 3*30 = 90m

Area = l*b

= 150*90

= 13500m^2

Hope it helps :)
