Question

how do i solve this? i'm really confused, please send help :

Answer 1

Given that length=(x+6)cm

and breadth=(x+1)cm

A.T.Q.

(x+6)×(x+1)=66

x²+x+6x+6=66

x²+7x+6=66

x²+7x=66-6

x²+7x-60=0

Answer 2

first putting value of ( x + 1 ) =0 =x=(-1) then put value. on information. (-1) ^2 + 7×(-1) -60 = 1-7 -60 =1-67 = -66. then follow this process in second value of x and again put value on given information. then given area and equate both the value of x with area. hope this will help you..
