5. A certain wall is 13' by 9'. A can of paint will cover 50 square feet. Will it be enough? Explain.
Area or Perimeter
Answer ______________
Area = length times width
Is there enough paint?
A=L×W
A=9×13
A=117 sq.ft
It will not be enough because the area of a wall is 117 sq.ft but a paint can cover only 50sq.ft
How would I explain this? Would my work count as an explanation?
No because it 117 and that not enough
A = lw
A = 13 ⋅ 9
A = 117 ft^2
Yes because 44 is close to 50
To determine if the can of paint will be enough to cover the wall, we need to calculate the area of the wall first. The formula to calculate the area of a rectangle is length multiplied by width.
Given that the wall is 13 feet by 9 feet, we can use the formula:
Area = length * width
So, the area of the wall is:
Area = 13 ft * 9 ft = 117 square feet
Now, we compare the area of the wall (117 square feet) with the coverage of one can of paint (50 square feet). Since 117 square feet is larger than 50 square feet, one can of paint will not be enough to cover the entire wall.
Therefore, in this case, a single can of paint will not be sufficient to cover the entire wall.
