Question

What is the length of the longest side ?

Answer 1

11 feet (Option C)

Explanation:

Let the longer side be l and the shorter side be b.

We know that,

→ Perimeter of rectangle = 2 ( longer side + shorter side )

Here,

• Perimeter of rectangle is 32 feet.

→ 32 = 2 (l + b)

→ 32 = 2l + 2(5)

→ 32 = 2l + 10

→ 32 - 10 = 2l

→ 22 = 2l

→
`\sf (22)/(2)` = l

→ 11 = l

→ 11 feet = longer side

`\therefore` Length of the longer side is 11 feet.
