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

= \(\frac{1}{2}\times2\times3\)

= \(3\; cm^2\)
