Q. A square garden has sides that are

20

feet long. Fencing costs

\$1.00

per foot. How much would it cost to put a fence around the garden?

\newline

\$

_____

Calculate Perimeter of Square: To find the total cost of the fencing, we need to calculate the perimeter of the square garden. The perimeter of a square is given by the formula $P = 4s$ , where $s$ is the length of one side of the square.
Substitute Side Length: Since each side of the square garden is $20$ feet long, we can substitute $s$ with $20$ in the formula to find the perimeter: $P = 4 \times 20$ .
Calculate Total Cost: Calculating the perimeter, we get $P = 80$ feet.
Multiply Perimeter and Cost: Now that we know the perimeter, we can calculate the total cost of the fencing. The cost of fencing is given as $\$1.00$ per foot. Therefore, the total cost $C$ is equal to the perimeter $P$ times the cost per foot.
Calculate Total Cost: Multiplying the perimeter by the cost per foot, we get $C = 80 \times \$1.00$ .
Calculate Total Cost: Multiplying the perimeter by the cost per foot, we get $C = 80 \times \$(1.00)$ . Calculating the total cost, we get $C = \$(80.00)$ .
