Question

A parallelogram has a perimeter of 43.6 centimeters. Two of the sides are each 1.2 centimeters long. What is the length of each of the other two sides?

Answer 1

The other two sides are 20.6 cm

Explanation:

A parallelogram are always 2 pairs of congruent sides so with that being said the parallelogram perimeter is as follows

P = 2l + 2w

So lets solve

43.6 = 2(1.2) + 2(w)

43.6 = 2.4 + 2w

-2.4 -2.4

41.2 = 2w

41.2/2 = 2w/2

20.6 = w

Answer 2

The length of the two other sides combined is 43.6-1.2-1.2=41.2
The length of each of the two other sides is 41.2/2=20.6
