Question

The adjacent sides of a parallelogram are
in the ratio of 5 : 7. If the perimeter of the
parallelogram is 168 m then the measures
of its sides :​

Answer 1

Answer:

Given : ratio of the adjacent sides

5:7

perimeter of the parallelogram = 168

Step-by-step explanation:

Let the given ratios be 5x and 7x

A/Q

5x+7x+5x+7x = 168

or, 24x = 168

or, x = 168/24

or, x = 7

Now, 1st side = 5x = 5x7 = 35 m

2nd side = 7x = 7x7 = 49 m ANS.

Answer 2

Answer:

35m and 49m

Step-by-step explanation:

Perimeter- 168m

As opposite sides of a parallelogram are equal, the perimeter is 2(a+b) when a and b are adjacent sides

Let's take the common factor as 'x'

Therefore, the sides will be 5x, 5x, 7x, 7x

Finding perimeter,

Perimeter=2(a+b)

168=2(5x+7x)

168=2(12x)

168=24x

168/24=x

x=7

Now as we know the first side to be 5x, the value of it will be 5*7=35m and the adjacent side as 7x, the value of it will be 7*7=49m
