Question

Find the area of a triangle base is 3 height is 11

Answer 1

we know that

The formula to calculate the area of a triangle is equal to

$A=\frac{1}{2}bh$

where

b is the base of the triangle

h is the height of the triangle

in this problem we have

$b=3\ units\\h=11\ units$

substitute the values in the formula

$A=\frac{1}{2}*3*11$

$A=16.5\ units^{2}$

therefore

the answer is

the area of the triangle is equal to $16.5\ units^{2}$

Answer 2

A=1/2*b*h

A=1/2*3*11

A=1/2*33

A=16.5 

I hope this helps!
