Question

The ratio of two adjacent sides of a parallelogram is 2:3.Its parimeter is50cm.Find its area if altitude corresponding to larger side is 10 cm

Answer 1

b/l = 2/3
where l is length and b is breadth
so l= 1.5 b
2(l+b)= 50
l+b=25
on subsisting the value of l
we get
1.5b + b = 25
2.5b = 25
b= 10
so l= 15
given the altitude is 10
so area = longest side * altitude
area =15*10= 150 cm²

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
