Question

A Rectangle has perimeter 50m. If its length and width are in the ratio 2:3, what is its area?

Answer 1

Step-by-step explanation:

here perimeter =50 m

we know that perimeter of a rectangle= 2(l+b)=50m

let length=3x and wide= 2x

so 2(3x+2x)=50

2(5x)=50

5x=50/2

5x=25

x=25/5

x=5

therefore, length = 3(5)=15 and width=2(5)=10

now area of a rectangle = l× b

15×10=150m
