Answer:
42.25cm^2
Step-by-step explanation:
8+5+8+5 = 26
26/4 = 6.5
6.5x6.5 = 42.25
subsitute x = 6 into the lengths
3(6) -7
18 - 7
11cm
(6) + 5
11cm
therefore it is a square when x = 6 because the sides are all equal
If a dime equals 10¢, and 10 dimes equals 100¢ (or $1) you need to divide.
$90.10/10¢=90.1 dimes you need I think.
Hope this helps
