a) 30cm²
b) 8.75cm²
c) 30cm²
Step-by-step explanation:
a) Area of a triangle = 1/2 × base × perpendicular height
= 1/2 × 12 × 5
= 30cm²
b) Area of a triangle = 1/2 × base × perpendicular height
= 1/2 × 3.5 × 5
= 8.75cm²
c) Area of a triangle = 1/2 × base × perpendicular height
= 1/2 × 5 × 12
= 30cm²
