Question

Solve for the base of a triangle where the height is 16cm and area is 104 cm2. What is the base?

Answer 1

13cm

Explanation:

104 × 2 = 208

208 ÷ 16 = 13cm

(13 × 16) ÷ 2 = 104cm²

Answer 2

13 cm

Explanation:

Area = 1/2×base×height

Formula for area:

• S = 1.2bh

Solving for b:

• b = 2s/h
• b = 2*104/16 = 13 cm

Answer is 13 cm
