First, let's write an equation for the problem.

Now, all you have to do is solve it.

=
16Each side is 16 meters. I hope this helps!
Answer:
34.84
Step-by-step explanation:
5.2 times 6.7= 34.84
Answer:
7(x+5)-(2xy^2)
that's how you would write the equation
16. It is the only even number in the group. I know this because:
25/2 = 12.5
16/2 = 8
49/2 = 24.5
63/2 = 31.5
81/2 = 40.5
:) Hope I helped
The 65 tens blocks can be solved by doing 65x10 which is 650. the 7 ones blocks can be solved by 1x7 which is 7 so you then add up 650 and 7 to get a grand total of 657
