Question

Gabriel is designing a rectangular planter box for their garden. It needs to cover an area of 15 1/2 m. Gabriel wants it to be 7 3/4m long. How wide does the planter box need to be?

Answer 1

Answer:

2m wide

Step-by-step explanation:

$a=lw$

$15\frac{1}{2} =7\frac{3}{4} w$

$\frac{31}{2} =\frac{31}{4} w$

$w=\frac{\frac{31}{2} }{\frac{31}{4} } =\frac{(31)(4)}{(31)(2)} =2$

wide = 2m

Hope this helps
