Question

Find the perimeter and area of square whose side is 12m 50cm

Answer 1

Answer:

50m

Step-by-step explanation:

perimeter of square=2(a+a)

=2(2a)

=4a

=4*12.5m

50m

Answer 2

The perimeter of square = 50 m and  the area of square = $156.25m^{2}$.

Step-by-step explanation:

Given,

The side of square = 12 m 50 cm = 12 m + 0.5 m = 12.5 m

To find, the perimeter and area of square = ?

We know that,

The perimeter of square = 4a

Where, a is the side of square

The perimeter of square = 4 × 12.5 m = 50 m

And,

The area of square = $a^{2}$

$= 12.5^{2}=12.5\times 12.5=156.25m^{2}$

Hence, the perimeter of square = 50 m and  the area of square = $156.25m^{2}$.
