Question

The area of a square, life-sized chess board is 256 square feet. What is the length of one of its sides? a) 16 feet b) 12 feet c) 8 feet d) 4 feet

Answer 1

16 feet

Explanation:

The area of a quadrilateral is defined by Length * Width.

In the case of a square, where all side lengths are equal, this can be written as Area = Length * Length, or Length squared.

Because of this, the equation for this problems could look like this:
x^2 = 256

Squaring both sides equates to

x =
`√(256)`

Taking the square root of 256 will provide the answer of 16 feet.

Answer 2

Explanation:

The answer is a) 16 feet

Because a square has equal sides the length and width would be the same

Meaning it would be....

16 x 16= 256

I hope that helps!!!
