The perimeter of Dawna's new flat screen television is 112 inches. The ratio of its length to width is 4:3. Write and solve an algebraic equation to determine the dimensions of the television. I need to know ASAP!!!

The dimensions are length=32 inches and width=24 inches

Step-by-step explanation:

Recall that perimeter of a rectangle is

The ratio of its length to width is 4:3.

This implies that,

We substitute P=112 inches, and l in terms of w to get;

The length is

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
