Question

What is the area of a square thats sides are 3 times the length of a square with an area of 25

Answer 1

The area is 225 square units

Explanation:

The first thing we must do is calculate the value of the side of the triangle with the area of 25, knowing that the formula for the area of the square is as follows

`\begin{gathered} A=l^2 \\ A=25,\text{ replacing} \\ 25=l^2 \\ l=\sqrt[]{25} \\ l=5 \end{gathered}`

Now, if the new square its side is 3 times as long, then:

`\begin{gathered} 5\cdot3=15 \\ l=15,\text{ replacing:} \\ A=15^2 \\ A=225 \end{gathered}`
