Question

The perimeter of rectangular park is 450m. The length of the sides is in the ratio 3:2. Find the area of the rectangle.

Answer 1

Answer:

let the first side be 3x and second side be 2x.

by the condition,

or, 3x+2x = 450

or, 5x = 450

or, X = 450/5

or, X = 90

length of first side= 3x= 3*90=270m

length of second side= 2x = 2*90 = 180m

so, take 270m as length and 180m as breadth.

area of the rectangle= l*B= 270*180= 48600metre square

ANS- the area of the rectangle is 48600metre square
