Question

find the perimeter and area of a square whose side measure in 1 m 20 CM

Answer 1

first conversion of m into cm = 1m = 100cm
now perimeter of square = 4 × side
= 4 × 120
= 480
so the perimeter = 480 cm
now the area of square = side × side
= 120 ×120
= 14400 sq. cm.
so the area = 14400 sq. cm.

Answer 2

$\huge{\green{\boxed{\green{\boxed{\red{\textsf{Solution}}}}}}}$

=> 1 m = 100 cm

=> So, the side measure = 120 cm

=> PERIMETER of the SQUARE = Side × 4

=> 480 cm

=> $\large{\green{\boxed{\green{\boxed{\red{\textsf{4m \: 80cm}}}}}}}$

=> 4 meter 80 cm is the perimeter of the SQUARE

=> Area = Side × Side

=> 120 × 120

=> 14400

=> $\large{\green{\boxed{\green{\boxed{\red{\textsf{1.44sq.m }}}}}}}$

=> 1.44 sq.m is the area of the SQUARE.

∴$\textbf{\large{The\:area\:is\:1.44sq.m}}}$

∴$\textbf{\large{The\: PERIMETER\:is\:4m80cm}}}$
