A rectangle has a length of 3.6 in, and a perimeter of 16.8 in.

zhannawk [14.2K]

Answer:

Width = 4.8 inches

Step-by-step explanation:

The perimeter of a rectangle is given by the formula:

$P=2l+2w$

Where

P is perimeter

l is length

w is width

Given length = 3.6 and perimeter = 16.8, we plug them in into the formula and figure out the width, w. Process shown below:

$P=2l+2w\\16.8=2(3.6)+2w\\16.8=7.2+2w\\16.8-7.2=2w\\9.6=2w\\w=\frac{9.6}{2}\\w=4.8$

Hence, the width is 4.8 inches

What is -0.6(r+0.2) = 1.8 ???

lana66690 [7]

Answer:

r = -3.2

Step-by-step explanation:

-0.6(r+0.2) = 1.8

Divide by -.6

-0.6/-.6(r+0.2) = 1.8/-.6

r+.2 = -3

Subtract .2 from each side

r+.2-.2 = -3-.2

r = -3.2
