Question

ili ) The ratio of two sides of a parallelogram is 2:5 and its perimeter is 70 cm. Find
the sides of a parallelogram​

Answer 1

Answer:

ANSWER

If the two sides have a ratio of 3:4 that means their sides can be represented as 3x and 4x.

⇒ Perimeter of parallelogram =2(3x)+2(4x)

⇒ 112=6x+8x

⇒ 112=14x

⇒ x=8cm

The length of the sides are,

⇒ 3x=3×8cm=24cm

⇒ 4x=4×8cm=32cm

∴ The length of the smallest sides of the parallelogram is 24cm

Answer 2

Answer:

5l=2b

l=2b/5

2l+2b=70

4b/5 +2b=70

~~~b=25~~~l=10
