A rectangular yoga mat has a perimeter of 179 inches. The width of the mat is eight less than half the length. Find the width, i
lianna [129]

Answer:

The width is 24.5in

Step-by-step explanation:

The perimeter of the rectangular yoga mat can be found using the formula;

P=2l+2w.

\Rightarrow 179=2l+2w...(1).

It was given that the width of the mat is eight less than half the length.

w=\frac{1}{2}l-8...(2)

We put equation (2) into equation (1) to get;

179=2l+2(\frac{1}{2}l-8).

\Rightarrow 179=2l+l-16.

\Rightarrow 179+16=2l+l.

\Rightarrow 3l=195

Divide both sides by 3;

l=65

We put l=65 into equation 2 to get;

w=\frac{1}{2}\times65-8

w=32.5-8

w=24.5in
