Question

Using the formula A = lw, find the are of the rectangle

\[9x ^{2}\] this is the length
\[5x ^{2}\] this is the height

Answer 1

\[area=length \times wide...or...area = length \times height\]
you mean 5x^2 = wide ?

Answer 2

\[5x^{2}\]

Answer 3

is the height

Answer 4

Substitute in your length and width values. \[A=9x^2(5x^2)\]Evaluate. Properties of exponents may help you here:\[x^ax^b=x^{a+b}\]

Answer 5

I think I got it \[45^{4}\]

Answer 6

I multiplied the number and added the exponents

Answer 7

\[9x^2(5x^2)=9^15^1x^2x^2\]
