A roll of gasket material is 16 in wide. What length is needed to obtain 15 sq ft of the material? (Careful: The numbers are no

irakobra [83]

Answer:

l = 11.19 feet

Step-by-step explanation:

Given that,

The width of a roll of gasket material, b= 16 inches

We need to find the length needed to obtain 15 sq ft of the material.

We know that,

1 foot = 12 inches

⇒ 16 inhces = 1.34 feet

For a rectangular shaped object, area is given by :

A = l×b

$l=\dfrac{A}{b}\\\\l=\dfrac{15}{1.34}\\\\=11.19\ ft$

So, the required length is 11.19 feet.
