Chapter 11.5, Problem 7PSA

To determine

To find : The apothem of a square with area given as $36{\text{ mm}}^2$

Answer to Problem 7PSA

The length of apothem is $(h)=3\text{ mm}$

Explanation of Solution

Given information : The area of the square is, $(A)=36{\text{ mm}}^2$

Formula used : The apothem of a square $(h)=\frac{\sqrt{A}}{2}$

Calculation : We substitute the value of $A=36$ in the equation, and we get

  $h=\frac{\sqrt{A}}{2}$$h=\frac{\sqrt{36}}{2}=3\text{ mm}$
