Given:

Length of the base of the triangle = 40 cm

Height of the triangle = 15 cm

Formula Used:

Area of a triangle = (1/2) × base × height

Calculation:

Base = 40 cm

Height = 15 cm

Area = (1/2) × base × height

Area = (1/2) × 40 × 15

Area = 20 × 15

Area = 300 sq cm

The area of the triangle is 300 sq cm.
