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
Answer:
the answers are 12.5, 5, 2, 0.8 and 0.32
Step-by-step explanation:
2(0.4)^-2
=2(6.25)
= 12.5
2(0.4)^-1
= 2(2.5)
=5
2(0.4)^0
=2(1)
=2
2(0.4)^1
=2(0.4)
=0.8
2(0.4)^2
=2(0.16)
=0.32
