Question

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

Answer 1

How to find,

Let the nomber x

3x, 2x

Solution,

→ 3x*2x = 150

→ 6x² = 150

→ x² = 25

→ x = 5

Hence,

The length of it,s sides are,,

3x→3*5= 15

2x→2*5=10

➪15,10

Answer 2

Answer:

length - 75 sq.cm

Step-by-step explanation:

let the length of rectangular piece of paper 3x

let the breadth of rectangular piece of paper 2x

Area of rectangular piece - 150 sq. cm

Length*Breadth - 150 sq.cm

3x*2x - 150 sq.cm

6x - 150 sq.cm

x - 150/6 sq.cm

x - 25 sq.cm

length - 3*25 - 75 sq.cm

breadth - 2*25 - 50 sq.cm
