Question

(01.06 mc) bob fenced in his backyard. the perimeter of the yard is 22 feet, and the length of his yard is 5 feet. use the perimeter formula to find the width of the rectangular yard in inches: p = 2l + 2w. 6 in. 12 in. 72 in. 144 in.

Explanation:

Step1: Substitute values into formula

Given $P = 22$ feet and $L = 5$ feet into $P=2L + 2W$. So, $22=2\times5 + 2W$.

Step2: Simplify the equation

$22 = 10+2W$. Subtract 10 from both sides: $22 - 10=2W$, which gives $12 = 2W$.

Step3: Solve for $W$ in feet

Divide both sides by 2: $W=\frac{12}{2}=6$ feet.

Step4: Convert feet to inches

Since 1 foot = 12 inches, then $W = 6\times12 = 72$ inches.

Answer:

72 in.
