Question

Write and solve an equation to answer the question.

The perimeter of the Puerto Rican flag is 150 inches. What are the dimensions of the flag?

Answer 1

`length = 45 \\ width = 30`

Explanation:

Perimeter =150 , length = 3/2y , width = y .

Perimeter of rectangle = (length + width ) × 2

`150 = ( (3)/(2) y \: + y) * 2 \\ \\ 150 = ( (3)/(2) y+ (2)/(2) y ) * 2 \\ \\ 150 = ( (5)/(2) y) * 2 \\ \\ 150 = 5y \\ \\ y = (150)/(5) \\ \\ y = 30`

width = y = 30

`length = (3)/(2) y = (3)/(2) * 30 = 3 * 15 = 45`
