Question

If the unit of length is tripled the numeical value of area of square will be

Answer 1

Answer:

The area "A" of a side square 'a' is given by

A=(side)^2=a^2

Let S be the length of the square

Area of square now will be =SL

Therefore A=(SL)^2

If unit of length is tripled then

A=(S3L)^2

=27S^2L^2
