Question

What is the area of the right-angled triangle $\Delta MNO$, right angled at N.

• A. $\frac{1}{2}\times MN\times NO$
• B. $\frac{1}{2}\times MN\times MO$
• C. $\frac{1}{2}\times MO\times NO$
• D. $MN\times NO$

Answer 1

The correct option is A $\frac{1}{2}\times MN\times NO$

Area of a triangle = $=\frac{1}{2}\times base\times height=\frac{1}{2}\times MN\times NO$.
