Question

Find the area of each of the following triangles:

Answer 1

Area of triangle $=\frac{1}{2}\times base\times hieght$

(a) height $=3cm$, and base $=4cm$

Area of triangle $=\frac{1}{2}\times 4\times 3=6c{m}^2$

(b) Height $=3.2cm$, and base $=5cm$

Area of triangle $=\frac{1}{2}\times 5\times 3.2=8c{m}^2$

(c) height $=4cm$ and base $=3cm$

Area of triangle $=\frac{1}{2}\times 3\times 4=6c{m}^2$
