Question

Find the altitude of the triangle if its area is $25acres$ and base is $20m$.

Answer 1

Given area of the traingle $=25acres$

$1acre=4046.86m^2\Rightarrow 25\times 4046.86m^2$

base$=20m$

let altitude be $a$

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

$2\times 4046.86m^2=\frac{1}{2}\times 20\times a$

$a=10117.15m$
