Question

Answer the questions below.(a) The perimeter of a rectangular parking lot is 314 m.If the width of the parking lot is 71 m, what is its length?Length of the parking lot: 0 m(b) The area of a rectangular pool is 8075 m.If the length of the pool is 95 m, what is its width?Width of the pool: m

Answer 1

We have to use the perimeter formula for rectangles

$P=2(w+l)$

Where P = 314 m and w = 71 m.

$\begin{gathered} 314=2(71+l) \\ \frac{314}{2}=71+l \\ 71+l=157 \\ l=157-71 \\ l=86 \end{gathered}$

Hence, the length is 86 meters.
