Question

the area of a rectangle is x^2 + 7x + 12. if its breadth is x + 4, find it's length​

Answer 1

Answer:

let breath be ;a

area of rectangle=length x breadth

x*2+7x+12= x+4 *a

a= x*2+7x+12/x+4

a= x+3

Answer 2

Answer:

area of rectangle =x^2+7x+12

length=x+4

breadth=b

area = l.b

x+4.b=x^2+7x+12

x.b=x^2+7x+12-4

x.b=x^2+7x+8

b=x+7x+8
