Scott has verified that the window is a rectangle. Side AB is half of the length of side AC. If the perimeter of the window is 120 ft., what are the lengths of side AB and side AC?

AB = 20 ft

AC = 40 ft

Step-by-step explanation:

==>Given:

Rectangular window ABCD, where,

side AB = ½ of side AC

Perimeter = 120ft

==>Required:

Length of side AB and side AC

==>Solution:

Let AB = x

If x = ½ of AC

AC = 2x

Perimeter = 2(AB + AC)

Thus,

120 = 2(x+2x)

120 = 2(3x)

120 = 6x

Divide both sides by 6 to solve for x

120/6 = x

20 = x

AB = x = 20 ft

AC = 2x = 2(20) = 40ft

step-by-step explanation:

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
