Mathematics Formula Quiz

A rectangle is a two-dimensional polygon with four straight sides. What is the formula for perimeter of a rectangle?

• P = (L x W) x 2

• P = (L + W) x 2

• P = 1 L + 2 W

• P = (2 L + 2 W) x 2

What is the formula for Simple Interest (S.I.)?

• S.I. = P x R x T

• S.I. = P + R + T

• S.I. = (P x R x T) / 100

• S.I. = (P x R x T)/ 1000
