Question

The ratio of two adjecent side of parallelogram is 2:3.its perimeter is 50 cm.find its area if altitude corresponding to larger side is 10cm?

Answer 1

2(2x+3x)=50
3x+2x=50÷2
3x+2x=25
5x=25
x=5
length of larger side =3×5=15cm
area=b×h
=15×10
=150cm^2
I think is right

Answer 2

Answer:

150

Step-by-step explanation:

Let the ratio constant be x

According to question

2x+3x+2x+3x=50

10x=50

x=5

Sides=10 and 15

Area of parallelogram=base *height

10*15=150
