Question

The area of a triangle is equal to $175c{m}^2$. Find the height of the triangle if its base = $14cm$.
Given: Area of a triangle = $\frac{1}{2}\times base\times height$.

• A. 15cm
• B. 20cm
• C. 25cm
• D. 30cm

Answer 1

The correct option is C 25cm

Area of a triangle = $\frac{1}{2}\times base\times height$
Let the height of the triangle = $hcm$
$\therefore$ 175 = $\frac{1}{2}\times 14\times h$
$175=7\times h$
$h=\frac{175}{7}$ = $25cm$
Hence height of the triangle = 25 cm
