Calculate the Area of a Square: ABCD Vertex Problem

Question

Look at the square below:

Which expression represents its area?

00:00 Express the area of the square

00:03 Side length according to the given data

00:07 We'll use the formula for calculating the area of a square (side squared)

00:15 We'll substitute appropriate values and solve to find the area

00:23 Make sure to square both numerator and denominator

00:34 And this is the solution to the question

The area of a square is equal to the measurement of one of its sides squared.

The formula for the area of a square is:

$S=a^2$

Hence let's insert the given data into the formula as follows:

$S=\frac{10^2}{x^2}=\frac{100}{x^2}$

$\frac{100}{x^2}$
