Question

Length of a rectangle is (3p+4) cm and its breadth is (p - 5)cm, then find its area?​

Answer 1

Answer:

3p² - 11p - 20

Step-by-step explanation:

• length = (3p + 4)
• breadth = (p - 5)
• area of rectangle = length × breadth
• area of rectangle = (3p + 4)(p - 5)
• area of rectangle = 3p( p - 5) + 4(p - 5)
• area of rectangle = 3p² - 15p + 4p - 20
• area of rectangle = 3p² - 11p -20
