Question

Find the area of a triangle whose base is $18x$ and the corresponding altitude is $5y$ units.

Answer 1

As we know that,

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

Given:-

Base $=18x$ units

Altitude $=5y$ units

Therefore,

Area of triangle $=\frac{1}{2}\times 18x\times 5y=9x\times 5y=45xy\text{sq. units}$
