Question

Find the area of the triangle in which

A) Base $=42$cm and height $=25$ cm.

B) base $=16.8$ m and height $=75$ cm

C) base $=8$ dm and height $=35$cm

Answer 1

(A) Given Base =$42$ cm and height =$25$ cm

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

=$\frac{1}{2}\times 42\times 25$

=$525c{m}^2.$

(B)Given Base = 16.8 cm and height =75 cm.

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

$=\frac{1}{2}\times 16.8\times 75$

=$630c{m}^2$

(c)Given Base = 8 cm and height = 35 cm

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

=$\frac{1}{2}\times 8\times 35$

=$140c{m}^2$
