Calculate the perimeter and area of the following square if a= 19
2 answers:
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.
we are given
Area:
side=a=19
we know that
area of square = side*side
now, we can plug value
and we get
Perimeter:
perimeter=4a
