If you let the width be x, then the length will be 2x + 3. The perimeter P is
twice the width plus twice the length, i.e.,
P = 2*x + 2*(2x + 3) = 2x + 4x + 6 = 6x + 6.
So if the perimeter is 66 cm then 66 = 6x + 6 ---> 6x = 60 ---> x = 10 cm.,
and so if the perimeter is at most 66 cm., the width can be at most 10 cm..
Answer:

Substitute the values in the expression


Answer:
Area = 64
Step-by-step explanation:
area of a square = 
side length = 8
= 64
The tens place because 4 and 8, 8 is over 5 so u round up then it is 254 rounded to the tens 55
