Question

Chapter - Decimal
1) find the area of a square having each side of length:
i) 2.5 cm​

Answer 1

Answer:

Area of square= a^2

here a= 2.5cm

Area= a^2

area= (2.5)^2

Area=2.5×2.5 cm^2

Area = 6.25cm^2

Answer 2

Answer:

Hence, Area of square having side 2.5 cm will be 6.25 Sq. cm

Step-by-step explanation:

In context to question asked,

We have to determine the area of the square.

As per question,

We have,

Side of square = 2.5 cm

As we know that,

Square is a quadrilateral whose all sides are equal.

The area of square can be determined by using the formula $Area = Side^2$

So, for determining the area of square we will put the value of side of square in above formula,

Thus we will get the area of square as,

$Area = 2.5^2\\=>Area = 2.5\times 2.5\\=>Area = \frac{25}{10}\times \frac{25}{10} = \frac{5}{2} \times \frac{5}{2} = \frac{25}{4} = 6.25\:cm^2$
