Question

You want to find the area of a window to buy glass. It is a rectangle with a triangle on top, and you are trying to use this formula: Area 1/2(2 ft)³+(4 ft)(3 ft)

Answer 1

To calculate the area of the window, one should separately calculate the areas of the rectangle and the triangle using the correct formulas and then add them together.

Step-by-step explanation:

The student is asking about finding the area of a composite shape consisting of a rectangle with a triangle on top. To find the area, one must add the area of the rectangle to the area of the triangle. The area of the rectangle is found by multiplying the length by the width, whereas the formula for the area of the triangle is 1/2 × base × height. However, the formula provided in the question appears incorrect as it includes '1/2(2 ft)³', which is a volume calculation and not appropriate for finding areas. The correct formula to find the total area of the window would be obtained by calculating the area of the rectangle (length × width) and the area of the triangle (1/2 × base × height) separately and then adding both areas.
