Question

hi my question is
a square paper s sheet has 2/5 cm long side. find it perimeter and area
​

Answer 1

Answer:

hope this helps

Step-by-step explanation:

perimeter of a square = 4 * side

= 4 * 2/5

= 8/5 cm

area of a square= side²

=(2/5)²

=2² / 5²

= 4/25 cm²

Answer 2

Answer:

Perimeter = 1.6cm         Area = 0.16cm

Step-by-step explanation:

First, note that this sum would be easier if it was in decimals. So, let's convert it. $\frac{2}{5}$ to decimals = 0.4

Now, the perimeter of a square = length of one side x 4 (for the four sides of a square)

= 1.6

Now, the formula of area for a square is length x breadth. In a square, the length is the same as the breadth.

= 0.4 x 0.4

= 0.16
