A trapezoidal mural with bases 11m and 9m and height 6m needs to be painted. What is the cost of painting it if a box of paint in any color is $16 and with each box can be painted area of 12m2.
The answer is 80! :D Thanks Steve! <33
the answer is 80
I hope you are not the one who has already posted this several times, receiving an answer each time. It is
(11+9)/2 * 6 * 16/12
To find the cost of painting the trapezoidal mural, we need to calculate the area of the mural first.
The formula to find the area of a trapezoid is:
Area = (1/2) * (base1 + base2) * height
Given:
base1 = 11m
base2 = 9m
height = 6m
Calculating the area of the trapezoid:
Area = (1/2) * (11m + 9m) * 6m
Area = (1/2) * 20m * 6m
Area = 10m * 6m
Area = 60 square meters
Now, we need to determine how many boxes of paint are required to cover an area of 60 square meters.
Given:
Area covered by one box of paint = 12m2
Number of boxes required = Area of the mural / Area covered by one box of paint
Number of boxes required = 60m2 / 12m2
Number of boxes required = 5 boxes
Next, we need to calculate the cost of painting the mural.
Given:
Cost of one box of paint = $16
Total cost = Number of boxes required * Cost of one box of paint
Total cost = 5 boxes * $16
Total cost = $80
Therefore, the cost of painting the trapezoidal mural would be $80.
