Jeff wants to build a retangular fence in his yard for his dog. The yard is 35 feet by 40 feet. How much fencing must Jeff buy ?
You need to find the perimeter of this yard.
P = 2l + 2w
P = 2 * 35 + 2 * 40
P = 70 + 80
P = ?
p=150
Right. Jeff needs 150 feet of fencing.
To find out how much fencing Jeff needs to buy, we need to calculate the perimeter of the rectangular yard.
The perimeter of a rectangle is found by adding up the lengths of all its sides. In this case, we have a rectangle with sides measuring 35 feet and 40 feet.
To calculate the perimeter, we can use the formula: perimeter = 2(length + width).
Given that the length of the yard is 35 feet and the width is 40 feet, we can substitute these values into the formula:
perimeter = 2(35 + 40)
Simplifying the equation, we get:
perimeter = 2(75)
perimeter = 150 feet
Therefore, Jeff needs to buy 150 feet of fencing.
