Question

the side of a square is 2.5 cm find its perimeter and area
​

Answer 1

side of square=2.5

perimeter of square=4a

=4×2.5 cm

=10cm

area of square =Side×Side

=2.5×2.5

=6.25

Answer 2

Given:

• The side of a square is 2.5 cm

To Find:

• its perimeter and area

Solution:

➠ Perimeter of square = 4 × Side

$\longrightarrow \: \: \rm{ (4 \times 2.5)cm}$

$\space$

$\longrightarrow \: \: \rm{\red{10}\green{cm}}$

➠ Area = (side)²

$\longrightarrow \: \: \rm{ (2.5 × 2.5) sq. cm}$

$\space$

$\longrightarrow \: \: \bf{ \red{6.25 \green{ \: \: sq. cm}}}$

Therefore,

⚘Perimeter = 10 cm

⚘Area = 6.25 cm²
