Agardener uses 76 ft. of fencing to enclose a rectangular shaped garden. the width of the garden is 2 ft. shorter than 3 times it’s length. let x represent the length and write an equation to find the dimensions of the garden. what is the width?

The width of the rectangular garden is 28 feet

Step-by-step explanation:

Let

x ----> the length of the rectangular garden in feet

y ---> the width of the rectangular garden in feet

we know that

The perimeter of the rectangular garden is equal to

we have

so

simplify

---> equation A

---> equation B

solve the system by substitution

substitute equation B in equation A

solve for x

Find the value of y

 --->

therefore

The width of the rectangular garden is 28 feet
