Question

Find the area of a triangle whose:
(i) base - 2 m, height -1.5 m
(ii) base - 34 m and height - 90 cm.

Answer 1

(i) base $=2m$

height $=1.5m$

Area $=\frac{1}{2}\times base\times height$

$\frac{1}{2}\times 2\times 1.5$

$=1.5m^2$

(ii) base $=34m$

height $=90cm=0.9m$

Area $=\frac{1}{2}\times base\times height$

$=\frac{1}{2}\times 34\times 0.9$

$=15.3m^2$
