Chapter 11.1, Problem 25WE

To determine

To Find: The area of square.

Answer to Problem 25WE

  $A=\frac{d^2}{2}$

Explanation of Solution

Given: Length of the diagonal is $d$

Given: Diagonal= $d$

Area of square when the diagonal is given.

  $\begin{array}{l}$ A=\frac{1}{2}{(diagonal)}^2$A=\frac{d^2}{2}\end{array}$

Hence, the area of the square is $A=\frac{d^2}{2}$
