36 - 36 = 0

0 = 0

Find and simplify an expression for the area of five rows of x squares with side lengths of x centimeters.

Answers

Answer:

5x^(3) centimeter square.

Step-by-step explanation:

We are given that,

Number of rows having squares = 5

Length of each square = x cm

As, we know,

Area of a square = side^(2)

Thus, area of 1 square = x^(2)

As there are x squares in each row, we get,

Area of 'x' number of squares = x* x^(2) = x^(3)

Also, as there are 5 rows.

Thus, total area of 5 rows = 5* x^(3) = 5x^(3) centimeter square.

Hence, the required area is 5x^(3) centimeter square.
