Question

The perimeter of parallelogram is 84 cm find the length of the adjacent sides if their ratio is 8: 6

Answer 1

let the ratio be x
8x+6x=84
14x=84
x=84/14
4
8x=4×8=32
4x=4×4=16

Answer 2

Answer:

Step-by-step explanation:

The perimeter of parallelogram = 84...

Ratio....= 8:6.

Let the ratio be 8x and 6x.

The Perimeter of parallelogram = 2(a+b).....

84 = 2( 8x + 6x)

84 = 2 × 14x

84 = 28x

X = 84 / 28.

X = 3

The length of adjacent side = 1) 8x = 8×3 = 24..m.

2) 6x = 6×3 = 18m.
