To find the area of all of the figures, all you need to do is base x height or the length x width.
Your answers for 1-6 are all correct.
For 7-9, remember that the area is the length times the width.
7) length x width, 42 x 30=1260
8) 17 x 22= 374
9) Since the length and width are the same in a square just multiply the side by itself. 2.7 x 2.7= 7.29
Hope this helps.

The Smith Family is designing new plans for an in ground pool. Mr. Smith draws a rectangular shape with a length that is 5 feet

kumpel [21]

To solve this problem you must apply the proccedure shown below:

1- The formula for calculate the area of this rectangle is:

$A=LH$

Where $L$ is the length and $H$ is the heigth.

2. Let's call identify the heigth with the variable $x$ .

3. If the length is $5ft$ longer than the heigth, you have:

$L=x+5$

4. Therefore, you can write the following polynomial expression:

$A(x)=x(x+5)\\ A(x)=x^{2} +5x$

5. If you know the value of the heigth, you can susbstitute it into the polynomial expression shown above and you will obtain the area.

Therefore, the answer is: $A(x)=x^{2} +5x$
