Question

Jim is fencing a rectangular yard 36 feet by 28 feet. He has 150 feet of fencing and will be installing a 5 foot gate on one end. How much fencing will he have left?

Answer 1

For this case, the first thing we must do is find the perimeter of the rectangle.

For this, we use the equation:

$P = 2w + 2l$

Where,

• w: width of the rectangle
• l: length of the rectangle

Substituting values we have:

$P = 2 (36) +2 (28)\\P = 128 feet$

We add hour the amount of foot gate on one end:

$5 + P = 5 + 128 = 133 feet$

Then, the remaining amount of fencing is:

$150 - 133 = 17 feet$

Answer:

Jim has a remaining amount of 17 feet of fencing
