Step-by-step explanation:
SA=ph+2A, that is, perimeter × height+ twice area
p=21+20+29=70cm
h=22cm
70×22=1540cm
A=1/2 ×20×21=210×2=420
1540+420=1960cm2
The student went wrong in step three. the solutions should have been -3 and 5
I do not believe so but dont quote me on it.

Answer:
please find the solution:
Step-by-step explanation:
please find the correct question:
Given value:
should be divisible by 6 we are also given that 
and start with x = 0
=-2 which is not divisible by 6
x= 1
= 2 not divisilble by 6
x= 2
= 6 which is divisible by 6
x=3
= 10 not divisible by 6
x=4
= 14 not divisible by 6
x=5
= 18 which is divisible by 6
so such x are x = 2 and x = 5
