I dont understand this.

To find the area of a rectangle the formula is:

Area = length * height

A = L * H

In this case:

L = 3x

H = 2x

^^^In-put these values into the equation given above

A = 3x * 2x

Now you must multiply them together.

When multiplying numbers with variable(s) you multiply the number portion normally ( 3 * 2 = 6).

Multiplying variables is slightly different. The matching variables (x and x) will become one "x" and have an exponent attached to the x.

What will the exponent be? If a variable has no visible exponent it can be assumed that it has an exponent of 1. When multiplying variables the exponents on each variable will be sumed together and attached to the final variable:

= x²

Now combine the product of the numbers with the product of the variables:

Area = 6x²

Hope this helped!

well it says it can go 5 miles "per hour" so 5 miles would already be one hour now how much would 8 be?
