Calculate Square Area: Finding Area When Side Length is (x+y)

Question

Look at the following square:

Express the area of the square.

00:00 Express the area of the square

00:03 Side length according to the given data

00:07 Use the formula for calculating the area of a square (side squared)

00:13 Substitute appropriate values and solve to find the area

00:19 And this is the solution to the problem

Remember that the area of a square is equal to the side of the square raised to the 2nd power.

Formula for the square area:

$A=L^2$

We substitute our values into the formula:

$A=(x+y)^2$

$(x+y)^2$
