Question

Find the area of a rectangle whose length is (5x + 2) and breadth is
(3x - 2) *

Answer 1

$\sf are a = l \: \times \: b$

$⇒ (5x + 2)(3x - 2)$

$⇒15 {x}^{2} + 6x - 10x - 4$

$⇒15 {x}^{2} - 4x - 4$

Answer 2

Answer:

Step-by-step explanation:

 area of rectangle =lxb

                               =(5x+2)(3x-2)

                               =15x^2-10x+6x-4

                               =15x^2-4x-4
