Question

Find the perimeter and area of square whose side is 19cm.

Answer 1

Answer:

Side of square = 19 cm

Area of square = Side × Side

Area = 19 × 19 = 361 sq.cm

Perimeter of square = 4 × Side

Perimeter = 4 × 19 = 76 cm

Answer 2

SOLUTION

LENGTH(L)=19cm

AREA(A)=?

PERIMETER (P)=?

WE KNOW,

A=l^2

=l×l

=19×19

=361cm^2

NOW,

P=4l

=4×19

=76cm
