What is the area of a right triangle with side lengths 30, 40, and 50? A. 1,200 B. 1,000 C. 750 D. 600

600 D

Step-by-step explanation:

This is a 3:4:5 right angled triangle so base = 30 and height = 40

Area = 1/2 * 30 * 40

= 600

600 square units

Step-by-step explanation:

This being a right triangle makes finding the area easier. If, for example, we choose 30 as the shorter leg, then the base would be 40 and the hypotenuse 50.

A = (1/2) (base) (height) here becomes A = (1/2) (30) (40), or 600 square units.
