Question

The length of a rectangular room is 6 feet longer than twice the width. If the room's perimeter is 144 feet, what are the room's dimensions?
A) Width = 27 ft; length = 60 ft
B) Width = 33 ft; length = 39 ft
C) Width = 22 ft; length = 50 ft
D) Width = 44 ft; length = 100 ft

Answer 1

44ft by 100

Answer 2

Perimeter is adding all the sides together, so
2w+6+2w+6+w+w=144

Solve for w

Answer 3

6w+12=144

Answer 4

6w=144-12

Answer 5

22

Answer 6

Right, thats the width.

Since the length is 2w+6
length=2(22)+6
length=50 feet
