Question

Write and solve an equation to answer the question.

Answer 1

Answer:

$length = 45 \\ width = 30$

Step-by-step explanation:

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

Perimeter of rectangle = (length + width ) × 2

$150 = ( \frac{3}{2} y \: + y) \times 2 \\ \\ 150 = ( \frac{3}{2} y+ \frac{2}{2} y ) \times 2 \\ \\ 150 = ( \frac{5}{2} y) \times 2 \\ \\ 150 = 5y \\ \\ y = \frac{150}{5} \\ \\ y = 30$

width = y = 30

$length = \frac{3}{2} y = \frac{3}{2} \times 30 = 3 \times 15 = 45$
