for area of square in centimeter
length which is given as 18 DM
you would be knowing that 1dm=10cm
so multiplying the length by 10
we get ,
10×18=180
the formula for finding the area of square is
x^2
so putting the value in the formula we get
(180)^2
=32400
for perimeter of square the formula is
4a
so putting the value in it we get,
4×180
=720
