A rectangle's width is twice as long as its length. If the perimeter is 36 in., what is the length?

Bumek [7]

Okay here:

Let L be the length and W the width of the rectangle.

1. w=2•L
2. 2L+2W=36

Substitute eq. 1 into eq. 2,

2L+2•(2•L)=36

2L+4L=36

6L=36

L=9

Not done yet, then from eq. 1,

W=2•L
W=2•9
W=18 <------- Your answer. :)

mart [117]

Answer:

$38.57

Step-by-step explanation:

Make a proportion.

$\frac{27}{x} = \frac{70}{100}$

Cross multiply.

27 times 100 = 2700

2700 divided by 70 = 38.57142857

Round the result to the hundredths place.

38.57142857 ≈ 38.57
