Question

The formula for the area of a traingle is 1/2 bh, where b is the length of base of the traingle and h is the vertical height. Use the formula to find the height of a traingle with a base length of 8 inches and an area of 39 square inches.​

Answer 1

Explanation:

We know that

Area of triangle = ½ × b × h

39 = ½ × 8 × h

39 = 4h

39/4 = h

9.75 = h

Answer 2

• 9.75 in

Explanation:

• A = (1/2)bh

Given:

• A = 39 in²
• b = 8 in

Find h:

• h = 2A/b
• h = 2*39/8 = 39/4 = 9.75 in
