I need to draw a square with an area of 250 square cm. How long will each side be, rounded to one decimal place?

Sagot :

EXPLANATION

Given that the square has an area of 250 squared cm.

[tex]Area=250=\text{side}^2[/tex]

Applying the square root to both sides:

[tex]\sqrt[]{250}=side[/tex]

Switching sides:

[tex]\text{side}=\sqrt[]{250}=\sqrt[]{25\cdot10}=\sqrt[]{10\cdot5^2}=\sqrt[]{5^2}\cdot\sqrt[]{10}=5\sqrt[]{10}[/tex]

Each side will be:

[tex]\text{length}=5\sqrt[]{10}=15.8cm^2[/tex]
