Solve triangle base 10, height 6

Problem

$A = \tfrac{1}{2} b h,\ b=10,\ h=6$

Step-by-step solution

Apply: $A = \tfrac{1}{2} \cdot \text{base} \cdot \text{height}$ .
Substitute $b = 10$ , $h = 6$ : $A = \tfrac{1}{2} \cdot 10 \cdot 6$ .
Simplify: $A = 30$ .
Note: height must be perpendicular to the chosen base — not the slant length.

Answer

$A = 30$
