Question

if the area of a rectangular plot is 2400 meter square andit length s 1 1halftimes it breath then it perimeter is

Answer 1

Answer:

let its breadth =x mtr

its length =3/2*x mtr  

hence area = 3/2*x^2 square mtr  

3/2*x^2=2400

or x^2 =2400*2/3=1600

x= +40 (since side can not be negative )

so breadth =40 mtr

length = 3/2*40= 60 mtr
