Question

We need to make a square metal plate with area 150 square centimeters. How long will each side of the plate be?

Answer 1

Answer:

$s\approx12.25\text{ cm}$

Step-by-step explanation:

The area of a square is represented by the following expression:

$\text{area}=\text{side}\cdot\text{side}$

Then, if we have an area of 150 square centimeters, substitute into the formula and solve for side:

$\begin{gathered} 150=s^2 \\ s=\sqrt[]{150} \\ s=5\sqrt[]{6}\approx12.25\text{ cm} \end{gathered}$
