Question

Perimeter of a rectangle is 50 cm and the length and breadth are in the ratio of 3:2 respectively. What is the area of rectangle in sq cm?

Answer 1

Let 3x and 2x now 3x+2x×2=50cm
10x=50cm
X=5
3x=15cm
2x=10cm
Area=l×b
=15×10
=150cm square

Answer 2

(3x+2x)2=50

3x+2x=50/2

3x+2x=25

5x=25

X=25/5

X=5 we will need this unknown value to fine the length and breadth.

3x

X=5

Length is

3*5

Answer of the length is

15

2x

X=5

The breadth is

2*5

Answer of the breadth is

10

Area of the rectangle is l*b

Length is 15

Breadth is 10

15*10

The area of the rectangle is 150
