She needs to buy two 1 gallon cans
high 9 ft=1side=9ft
2 sides=18ft
140-18=122 122/2=61 the other side is 61ft
Area 61x9=549 squared ft
549/300=1.83 cans
She will need to buy two 1 gallon cans
Answer:
Step-by-step explanation:
Perimeter = 84 cm
2*(length + width) = 84
2* (2x - 8 + x - 2) = 84
2*(2x + x - 8 - 2) = 84 {bring like terms together}
2*(3x - 10) = 84 {add/ subtract like terms}
Divide both sides by 2

3x - 10 = 42
3x - 10 +10 = 42 + 10 {add 10 to both sides}
3x = 52
Divide by 3,

x= 17 1/3
Length = 2x - 8

The answer is the very last option.
