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

[tex] Area=a*a [/tex]

now, we can plug value

and we get

[tex] Area=19*19 [/tex]

[tex] Area=361 [/tex]

Perimeter:

perimeter=4a

[tex] perimeter=4*19 [/tex]

[tex] perimeter=76 [/tex]
