Answer:
20 3/4
Step-by-step explanation:
First, add together the whole numbers:
5 + 15
= 20
Then, add the fractions and decimals together:
Convert 1/4 to a decimal, which is 0.25
Add the decimals together:
0.25 + 0.5
= 0.75
Convert this to a fraction:
0.75 = 3/4
Then, add together 20 and 3/4
20 + 3/4
= 20 3/4

Answer:
12 ft
Step-by-step explanation:
Let the width of the room be represented by w. Then the length is (2w-2), and the area is ...
A = LW
264 = (2w-2)w
132 = w² -w . . . . . . . divide by 2, eliminate parentheses
132.25 = w² -w +.25 . . . . . add (-1/2)² to complete the square
√132.25 = w -0.5 . . . . . take the square root
0.5 +11.5 = w = 12 . . . . . add 0.5; use the positive root
The width of the living room is 12 feet.
