Question

A certain quadrilateral has two pairs of parallel sides. The opposite sides are equal in length. There are also 4 right angles. What is the total length of the shorter pair of sides, if the longer pair measures 16cm each, and the figure has a perimeter of 56cm?

Answer 1

12 + 12 = 24

Explanation:

P = 2L + 2W

P = 2*16 + 2W

P = 56

56 = 32 + 2W Subtract 32 from both sides

56 - 32 = 2W

24 = 2W Divide by 2

24/2 = 2W/2

12 = W

The answer you want is 2 * 12 = 24
