Question

The area of the following triangle will be

• A. $20$ square unit
• B. $40$ square unit
• C. $15$ square unit

Answer 1

The correct option is A $20$ square unit

We know the area of a triangle $=\frac{1}{2}\times h\times b$
Here, $h=4$ and $b=10$
So, the area $=\frac{1}{2}\times 4\times 10$
$=\frac{1}{2}\times 40$
$=\frac{40}{2}$
$=20$ square unit
