Question

the sides of a rectangle piece of paper are in the ratio 2 ratio 3 if the area is 150 square cm find the length of its sides

Answer 1

let 2x&3x
6x²=150 (Area=l×b)
so x=5
put in above 10 &15 length is 15 and breadth is 10

Answer 2

Here is your solution

Given :-

The ratio of length and breadth of the given rectangle is 2:3

Let the length and breadth be 3x and 2x .

as area of rectangle = length × breadth

=>150= 6x^2 =
=> 150/6 =x^2
=> x = 5

length = 2x =2×5=10cm

hope it helps you
