Question

The length of a rectangle is three times its width. If the area of the rectangle is 75 yd^2, find its perimeter

Answer 1

Kinda like the last one,
L=3W.... so

(3W)x(W)=75 to find W. Then Multiply Your W by 3 to find L.

Answer 2

would it be 4w=75? no right??

Answer 3

WxW is \[W ^{2}\]

Answer 4

whats 3w^2 divided by 75..

Answer 5

\[\frac{ 3W^2 }{ 3 }=\frac{ 75 }{ 3 }\]

Answer 6

divide both sides by 3, so it is 75/3 = 25

which leaves you with \[W= \sqrt{25}\] so get rid of the exponent.

\[W=5\]

Answer 7

w=5?

Answer 8

Yea

Answer 9

so L=15

Answer 10

Yep

Answer 11

then to find the perimiter do you still multiply L & W?

Answer 12

and get 75

Answer 13

So now do P=2L+2W, to find your perimeter.

Answer 14

thats the area. how do i get perimiter

Answer 15

p=40?

Answer 16

Yea
