A- 300mm

B- 60 mm

C- 150 mm

D- 375 mm

Answer 1

150

Explanation:

A=B*H/2

A=15*20/2

A=300/2

• Area of a Triangle: A = 1/2bh

Explanation:

Step 1: Define Variables

Base b = 15 mm

Height h = 20 mm

Step 2: Find Area A

1. Substitute [T Area Formula]: A = 1/2(15 mm)(20 mm)
2. Evaluate Multiplication: A = 1/2(300 mm²)
3. Evaluate Multiplication: A = 150 mm²
