WebArea of the rectangle = length × breadth. = 10 × 3 cm 2. = 30 cm 2. Example 3. If the perimeter of a rectangle is 60 cm and its length is 5 times the width, find the area of the rectangle. Solution. Let the width be x. Length is 5 times its width, length = 5x. But the perimeter of a rectangle =2 (l + w) = 60 cm. WebMar 2, 2024 · When the length is 20 cm and the width is 10 cm, how fast is the area of the rectangle increasing? To set up the equation, I have A = l w. Differentiate both sides of the equation, I have d A d t = d l d t l + d w d t w = d A d t = ( 8.20) + ( 10.3) = 510. The solution manual says 140 and the equation is set d A d t = d w d t l + d l d t w.
