Formula for perimeter of a square: P = 4a
Formula for area of a square: A = a²
a is given as:
19
Plug this value for a into the above formulas to solve for perimeter and area.
P = 4a
P = 4(19)
P = 76
-----------------------------------------------------------------------------------------------------------------
A = a²
A = 19²
A = 361
Answer:
P = 76 units; A = 361 units².
The answer is D. SF is .4
