Question

The ratio of adjacent sides of a paralelogram is 2:3. Its perimeter is 50 cm. Find its area, if altitude
sponding to larger side is 10 cm​

Answer 1

Answer:

THE AREA OF THE PARALLELOGRAM IS 150cm²

LENGTH = 15cm

BREADTH = 10cm

Step-by-step explanation:

GIVEN RATIO = 2:3

PERIMETER = 50cm

SO,

LET THE COMMON RATIO BE x

SO,

LENGTH = 3x

BREADTH = 2x

PERIMETER = 2(LENGTH + BREADTH)

50cm = 2(3x+2x)

50cm = 2*5x

50cm = 10x

x = 50cm/10

x=5cm

2x=10cm

3x=15cm

SO,

GIVEN ALTITUTE = 10cm

SO,

WE KNOW,

AREA = BASE * HEIGHT

          = 15cm*10cm

          = 150cm²
