Question

Many practical applications require calculations of area. some of these calculations are straightforward, but others are more difficult, and it turns out that the idea of the definite integral can help us with the more difficult cases. let’s start with some familiar shapes. what is the area of a rectangle of length l and width w? express your answer in terms of l and w.

Answer 1

Area of a rectangle is given by multiplying the length and the width

Let's length be $'l'$ and width be $'w'$, then the area is

A = $l$ × $w$
