Question

Find the area of each of the following triangles:

Answer 1

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

(a) $Base = 4 \;cm, \;height= 3 \;cm$

$Area = \frac{1}{2}\times4\times3$

= $6\; cm^2$

---

(b) $Base = \;5 cm, \;height= 3.2 \;cm$

$Area = \frac{1}{2}\times5\times3.2$

= $8\; cm^2$

---

(c) $Base = 4 \;cm,\; height= 3\; cm$

$Area = \frac{1}{2}\times4\times3$

= $6\; cm^2$

---

(d)$Base = 3\; cm, \;height= 2\; cm$

= $\frac{1}{2}\times2\times3$

= $3\; cm^2$
