Question

PLS HELP! 10 POINTD ILL MARK BRAINLIEST

Answer 1

Answer:

Length is 18; width is 6.

Step-by-step explanation:

The formula for the perimeter of a rectangle is:

$P=2l+2w$

We are given that the perimeter is 48 feet. We are also told that the length is 3 times the width. In other words:

$l=3w$

So, substitute this for l and 48 for P. Thus:

$48=2(3w)+2w$

Distribute:

$48=6w+2w$

Combine like terms:

$48=8w$

Divide both sides by 8:

$w=6$

So, the width is 6.

The length as we know is 3 times the width, so the length is 3(6) is 18.

And we are done!

Answer 2

l=3w

3w(4)=48

12w=48

w=4

l=12

hope it helps

comment if u have any questions
