Question

Calculate the perimeter and area of the following square if a= 19

Answer 1

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.

Answer 2

we are given

Area:

side=a=19

we know that

area of square = side*side

$Area=a*a$

now, we can plug value

and we get

$Area=19*19$

$Area=361$

Perimeter:

perimeter=4a

$perimeter=4*19$

$perimeter=76$
