Answer:
Step-by-step explanation:
Assume the barn is 80 ft long, 50 ft wide, and 30 ft high
1. Area to paint
They will be painting two sides and two ends.
The sides are 80 ft × 30 ft.
The ends are 50 ft × 30 ft,
Area of sides = 2 × 80 ft × 30 ft = 4800 ft²
Area of ends = 2 × 50 ft × 30 ft = <u>3000 ft²</u>
Total area = 7800 ft²
2. Amount of paint needed
One gallon covers 420 ft².
They usually sell barn paint in whole gallons. Alexis will have to buy 19 gal of paint to cover the whole barn.
3. Total Cost
It costs $28 for one gallon of paint,
Answer:
ABC is not a right triangle
Step-by-step explanation:
The computation is shown below:
AC is
= Perimeter - (AB + BC)
= 22 - (8+5)
= 22 - 13
= 9
Now
= 9^2 + 13^2
= 81 +169
= 250
And, the perimeter is
= 22^2
= 484
Since the amount are not equivalent therefore ABC is not a right triangle
