Question

the ratio of two adjacent sides of a parallelogram is 3:4 and it's perimeter is 84 CM. find the sides of a parallelogram​

Answer 1

Answer:42

& 56

Step-by-step explanation:

Let the sides of the parallelogram=3x and 4x.

Perimeter=84cm

Since opposite sides of the parallelogram are equal,

2(3x+4x)=84

14x=84

x=14cm

Sides are 42 and 56

Answer 2

$\:\:\:\:\boxed{\huge\mathcal\red{ANSWER}}$

let the adjacent sides are 3x and 4x

now the perimeter=2×(3x+4x)=14x

now...

$14x = 84 \\ x = 6$

therefore the sides are...

$18 \: \: \: 24 \: \: \: \: 18 \: \: \: and \: \: \: \: 24 \: \:$
