Chapter 11.2, Problem 2PSA

To determine

To find : The area of the given triangle

Answer to Problem 2PSA

The area of the triangle is $A=120$

Explanation of Solution

Given information : The following information has been given

For base equals to $15$ , the height is $16$

For base equals to $20$ , the height is unknown

Formula used : The area of any triangle will be

  $A=\frac{1}{2}(base)(height)$

Calculation : We know that the area of a triangle can be calculated as

  $A=\frac{1}{2}(base)(height)$

Thus, substituting the values in the above formula, we get

  $A=\frac{1}{2}(15)(16)=120$
