Answer it:

17. Write the following as formulae.

a. The perimeter (p) of a square is four times its side (s) .

b. The amount (A) that has to be paid finally with interest (I) along with the principal (P) borrowed from a bank.

c. The speed (s) of a vhicle is obtained by dividing the distance travelled (d) by the time taken (t).

- Let 'p' be the perimeter of square and 's' be the length of its side, so the required formula is p= $4\times s$
- A = I+P
- s=$\frac{d}{t}$

Best Regards
