Find the area of each of the following triangles:

Solution

$Area of triangle = \frac{1}{2} \times Base \times Height$

(a) Base = 4 cm, height= 3 cm

Area $= \frac{1}{2} \times 4 \times 3$ = 6 cm²

(b) Base = 5 cm, height= 3.2 cm

Area $= \frac{1}{2} \times 5 \times 3.2$ = 8 cm²

(c) Base = 4 cm, height= 3 cm

Area $= \frac{1}{2} \times 4 \times 3$ = 6 cm²

(d)Base = 3 cm, height= 2 cm

Area = $\frac{1}{2} \times 2 \times 3$ = 3 cm²
