A family installed a triangular piece of glass in a rectangular wooden door of their home. The rectangular wooden door is 100 inches by 40 inches. The triangular glass has a base of 6 inches and a height of 8 inches. What is the area of the triangular glass portion of the door?
A.24
B.48
C.4,024
D.3,976
A
Both are right.
To find the area of the triangular glass portion of the door, we need to use the formula for the area of a triangle:
Area = 1/2 * base * height
In this case, the base of the triangle is 6 inches and the height is 8 inches.
So, the area of the triangular glass portion of the door is:
Area = 1/2 * 6 inches * 8 inches
= 24 square inches
Therefore, the correct answer is A) 24.
