Question

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

Answer 1

Let the length and width be 2a and 3a respectively

Area = 150

=> 2a × 3a = 150

=> 6a^2 = 150

=> a^2 = 25

=> a = 5

Length = 10 cm

Width = 15 cm

Answer 2

Let length and breadth of rectangke be 2x and 3x.
Area=150cm^2
2x*3x=150cm^2
6x=150cm^2
x=25
2*25=50
3*25=75
