The area of a triangle is 1 comma 440 cm squared The base of the triangle is 5 times the height. What is the height of the triangle?

Let the height be h centimeters, so the base is 5h. The triangle’s area is (base × height) ÷ 2, giving (5h × h) ÷ 2 = 1,440. Thus h² = 576, so h = 24 cm (the positive value for a length). The correct choice is 24 cm.
