Tristan wants to build a square garden in his backyard. if the garden is going to be 64 ft squared, how many feet of material will he need for the perimeter of the garden

Answer with Step-by-step explanation:

Tristan wants to build a square garden in his backyard.

Let the sides of the square garden be s.

If the garden is going to be 64 ft².

i.e. Area=64 ft²

and we know that

Area of square=Side²

So, s² =64

i.e. s=8 ft

We have to find the material needed for the perimeter of the garden

We know that perimeter of square=4×Side

                                                        = 4×8 ft

                                                        = 32 ft

Hence, material will he need for the perimeter of the garden is:

32 feet

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
