Answer:
Step-by-step explanation:
1. P = (width + lengh) * 2 = (23 + 10) * 2 = 33 * 2 = 66
A = width * lengh = 23 * 10 = 230
2. width = 7
P = (width + lengh) * 2 = ( 7 + 9) * 2 = 16 * 2 = 32

=

First, simplify

to

/ Your problem should look like:

=
Second, multiply both sides by 5. / Your problem should look like: 6 = 2n
Third, divide both sides by 2. / Your problem should look like:

= n
Fourth, simplify

to 3. / Your problem should look like: 3 = n
Fifth, switch sides. / Your problem should look like: n = 3
Answer:
n = 3
