Question

9. The perimeter of a square is 40 cm. Find its side and area.​

Answer 1

Step-by-step explanation:

Side of square = 40/4

=10cm

Area of square =10×10

=100cm^2

Answer 2

Answer:

Side of the Square = 10cm

$area \: of \: the \: square = {100cm}^{2}$

Step-by-step explanation:

Consider Side of Square = S

We know that

Side × 4 = Perimeter of Square

Then, According to question

S × 4 = 40cm

$s = \frac{40}{4} cm$

S = 10cm

Side = S = 10cm

We know that

Area of Square = Side × Side

Then,

Area of the Square = 10 × 10 =

${100cm}^{2}$
