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 ?
