Question

1. what is the perimeter of the rectangle?

area = 55 units$^2$
5
55 units
20 units
32 units
11 units

Explanation:

Step1: Find the unknown side length

Let the unknown side be $l$. Use area formula: $Area = l \times w$.

$$\begin{align} 55 &= l \times 5 \\ l &= \frac{55}{5} = 11 \end{align}$$

Step2: Calculate the rectangle's perimeter

Use perimeter formula: $P = 2(l + w)$.

$$\begin{align} P &= 2(11 + 5) \\ &= 2 \times 16 = 32 \end{align}$$

Answer:

32 units
