Question

What expression represents the area (A) of a triangle where the base (b) is 3 units more than its height (h)?

A) A = (h + 3) * h / 2
B) A = h (h - 3)
C) A = h * (h + 3) / 2
D) A = h * (h + 3)

Answer 1

The expression that represents the area (A) of the triangle is A = (h + 3) * h / 2.

Step-by-step explanation:

The expression that represents the area (A) of a triangle where the base (b) is 3 units more than its height (h) is A = (h + 3) * h / 2.

This formula is derived from the general formula for the area of a triangle, which is A = 1/2 * base * height. Since the base is 3 units more than the height, it is represented as h + 3.

To find the area of the triangle, you substitute the values for height and base into the formula and perform the necessary calculations.
