Width of the rectangle is 14 ft
Step-by-step explanation:
- Step 1: Let the width of the rectangle be x. Then length = 8 + x. Perimeter = 72 ft.
Perimeter = 2(length + width)
72 = 2 (8 + x + x)
72 = 16 + 4x
4x = 56
x = 56/4 = 14
∴ Width of the rectangle is 14 ft

If the pieces are cut in the ratio <span>3:5:7</span>, the proportion of each piece to the whole (represented by <span>3+5+7=15</span>) is:
<span><span>3/15</span>:<span>5/15</span>:<span>7/15</span></span>
First, convert the inches to feet also:
1 foot equals to 12 inches.
So 9 inches <span>=<span>9/12</span>×1=0.75</span> feet.
Thus, 33 feet and 9 inches equal <span>33+0.75=33.75</span> feet.
So,
<span>P=<span>3/15</span>×33.75=6.75</span> feet.
<span>Q=<span>5/15</span>×33.75=11.25</span> feet.
<span>R=<span>7/15</span>×33.75=15.75</span> feet.
You can check that these answers are correct by adding up the different pieces: <span>6.75+11.25+15.75=<span>33.75</span></span>
