Question

The desk has an area of 30 ft and the length of the desk is 5 feet what is the Perimeter, in feet?

Answer 1

Perimeter of desk is 22 feet

Solution:

Given that desk has area of 30 feet and length of desk is 5 feet

To find: perimeter of desk in feet

Since desk is of generally rectangular shape, we can use perimeter of rectangle formula

Let us first find the width of adesk

The area of rectangle is given as:

`\text {area of rectangle}=\text {length } * \text {width}`

Substitute area = 30 feet and length = 5 feet in above formula,

`30=5 * w i d t h`

`\text {width }=(30)/(5)=6 \text { feet }`

Thus width = 6 feet

The perimeter of rectangle is given as:

perimeter of rectangle = 2(length + width)

Substituting the length and width values we get,

perimeter of rectangle = 2(5 + 6) = 2(11) = 22 feet

Thus the perimeter of desk is 22 feet
