Problem |
The perimeter of a rectangle is 267 ft. The width of the rectangle is 1/7th of the perimeter. What is the length of the rectangle? |
|
2 |
Step |
The given values are |
perimeter 267 ft and the width of the rectangle is \$1/7\$th od the perimeter |
3 |
Formula: |
The perimeter of rectangle is |
P = 2[length + width] |
4 |
Hint |
Here, the width of the rectangle is \$1/7\$th od the perimeter |
\$(1/7) times P\$ |
5 |
Step |
Now substitute the perimeter value |
\$1/7 times 267\$ |
6 |
Step |
After simplification |
B = 38.14 ft |
7 |
Step |
Now substitute the values in the perimeter formula |
267 = 2[l + 38.14] |
8 |
Step |
After simplification |
133.5 = l + 38.14 |
9 |
Step |
After simplification |
l = 133.5 - 38.14 |
10 |
Step |
After simplification |
l = 95.36 ft |
11 |
Step |
The length of the rectangle is l = 95.36 ft |
|
