A rectangle has a perimeter of 103.6 inches and a base of 39 inches. What is the height?

rusak2 [61]

Answer:

12.8 IN.

Step-by-step explanation:

So, what exactly is perimeter?

Perimeter= 2L+ 2W

In this question we were given the length.ie.Base and the perimeter itself.

●Length is 39 In.

●Perimeter is 103.6 In.

●We don't know the width.

But, as per given the question, we know that;

1 length = 39 In.

2 lengths= 78 In.

Now that we know the total length we can find the total width.

See as follows,

103.6 - 78= 25.6

2 widths= 25.6

1 width= 25.6÷2

=12.8 In

olga55 [171]

The sale per linear feet is $16.75.

First, we need to find the total amount of sales, so we have to subtract the returns and discounts.

10342 - 217 - 599 = 9529

Now, divide this amount by the amount of linear feet.
9529 / 575 = 16.57
