The perimeter of a standard-sized rectangular rug is 44 feet. The width is 2 feet
1 answer:
Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2(l+b)
Let the length be x
then width = x-2
44 ft = 2(l+b)
44ft = 2(x + x-2)
44ft = 2(2x-2)
44 ft = 4x -4
44+4 = 4x
48 = 4x
x = 48/4 = 12
Length = <u>x = 12</u>
Width = <u>x-2 = 12-2 =10</u>
<u></u>
<u>Length is 12 and width is 10</u>
<u></u>
<u>check if its correct </u>
2(l+b) = 44
2(12+10)=44
2(22) = 44

196 + x = 500
Subtract 196 from both sides:
196 on the left is cancelled out, and you’re left with x = 304

Solution:
<u>Note that:</u>
<u>Use the equation above to solve for t.</u>
- 5t - 8 + 68 = 180
- => 5t + 60 = 180
- => 5t = 180 - 60
- => 5t = 120
- => t = 120/5 = 24
The value of t is 24.
