a rectangular mural is painted on a wall. if the mural is 12ft wide and covers 86.4sqft,what is the height of the mural?
Don’t You have to divide 86.4 by 12 ?
No
The formula for finding the area of a rectangle is:
A = 2h + 2w
You know the area and the width. Solve the equation for the height. If you post your answer, we'll be glad to check it.
To find the height of the mural, we can use the formula for the area of a rectangle: Area = Length × Width.
In this case, we know that the width of the mural is 12 feet and the area is 86.4 square feet. Let's assume the height is h.
So, we have the equation: 86.4 = h × 12.
To solve for h, divide both sides of the equation by 12: h = 86.4 / 12.
Calculating this, we get: h = 7.2 feet.
Therefore, the height of the mural is 7.2 feet.
The area of a rectangle is (length)(width)
so 86.4 = 12(length)
length = 86.4/12
Check your answer by multiplying what you got by 12
