Question

The sides of a rectangular piece of paper are in the ratio 2:3 if the area is 150sq.cm find the length of its sides

Answer 1

Let the sides of the rectangular piece of paper be 2x and 3x
Now Area of Rectangular paper = 150 cm^2
Therefore
Length*breadth = 150
2x*3x = 150
6x^2 = 150
x^2 = 150/6
x^2 = 25
x = 5
so, Length of rectangle = 2x = 2(5) = 10 cm
Breadth of rectangle = 3x = 3(5) = 15 cm
