Question

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

Answer 1

EXPLANATION

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

`Area=250=\text{side}^2`

Applying the square root to both sides:

`\sqrt[]{250}=side`

Switching sides:

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

Each side will be:

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