I copied and pasted, so lol
A bank is getting a new marble floor that is green and white. The width of the floor is 8 feet. A white marble triangle will extend 10 feet into the area. White marble costs $9.50 per square foot. How much will the white marble section cost?
Assuming the base of the triangle is the full 8ft width, then its area is
1/2 bh = 1/2 * 8 * 10 = 40 ft^2
So, what do you think?
Oh! So basically it's 40 x 9.50 ?
It's 380
To find the cost of the white marble section, we need to calculate the area of the triangle and then multiply it by the cost per square foot.
First, let's find the area of the triangle. The formula to calculate the area of a triangle is:
Area = (base * height) / 2
In this case, the base of the triangle is the width of the floor, which is 8 feet. The height of the triangle is given as 10 feet.
Area = (8 * 10) / 2
Area = 40 square feet
Now we can multiply the area of the triangle by the cost per square foot to find the total cost of the white marble section.
Total cost = Area * Cost per square foot
Total cost = 40 * $9.50
Total cost = $380
Therefore, the white marble section will cost $380.
