Question

A square sim card has a perimeter of 2.4 cm. Find its area

Answer 1

Answer:

Side= 2.4÷2

=1.2cm

Area = S×S

=1.2×1.2

=1.44cm²

Answer 2

Answer:

${0.36 \: cm}^{2}$

Step-by-step explanation:

Given, perimeter of square = 2.4 cm

i.e., 4a = 2.4 cm

a = 0.6 cm

We know that,

$area \: ofsquare = {a}^{2}$

that is,

$= {0.6}^{2}$

$= 0.36 {cm}^{2}$
