Jason has 144 feet of material to build a fence around a rectangular garden on his property. if the width of the fence must be 9 feet, what is the length of the fence in yards if he uses all 144 feet of material?
126 yards
63 yards
42 yards
21 yards

Option D is the correct answer.

Step-by-step explanation:

Jason has 144 feet of material to build a fence around a rectangular garden on his property.

Total material with Jason = 144 feet

Perimeter of rectangle = 144 feet

Perimeter of rectangle = 2 x ( length + width )

2 x ( length + width ) = 144

length + width = 72

Given that width is 9 feet

Substituting

            length + 9 = 72

            length = 63 feet

1 yard = 3 feet

              length = 63 feet = 21 yards

Option D is the correct answer.

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
