Question

find the perimeter of the parallelogram

 

 

 

18 1/3 inches   14 3/4 inches

Answer 1

Hi again Richard;

A parallelogram is a rectangle.  Henceforth, the formula for calculating the perimeter is the same...

perimeter=2(length+width)

perimeter=2(18 1/3 + 14 3/4)

Let's simplify the fractions.

Let's note that 3 x 4 =12.  Therefore (1/3)(4/4) is 4/12, and (3/4)(3/3)=9/12

Perimeter=2(18 4/12 + 14 9/12)

Perimeter=2(32 13/12)

Perimeter=2(33 1/12)

Perimeter=66 2/12

Perimeter=66 1/6
