Question

the measures of two adjacent sides of a parallelogram are in the ratio 17 : 7. If the second side measures 3.5 cm, find the perimeter of the parallelogram?

Answer 1

24 cm

Explanation:

Given that there is a parallelogram and adjacent sides are in the ratio

17:7

The second side =3.5cm

So we have x:3.5 = 17:7 where x is the unknown first side

Solve using ratio property to get

3.5(17) = 7x

Or x = 8.5 cm

Perimeter of parallelogram = sum of all sides

= 2(sum of one pair of adjacent sides)

=2(8.5+3.5)

=2(12)

=24 cm
