If the perimeter is 40in and the length is 12 what is the width and the area

If the shape is a rectangle, your formula for perimeter is 2L + 2W. Given that our perimeter is 40 and our length is 12, we can find the width. Here's how:
Multiply 12 by 2, since our formula is 2L + 2W.
Now we have 24, so subtract 24 from 40 and then divide by 2 to get our width.
40 - 24 = 16.
16/2 = 8.
Our width is 8in.
Now that we have our width, we can find the area. The formula for area is L x W.
Our length is 12, and our width is 8.
8 x 12 = 96.
Your area is 96 in^2.
I hope this helps!

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

0 = ( 2 - 4 ) ( p + q )0 = ( 2 - 4 ) ( 2 + 5 i ),   by multiplying these0 = ( 4 + 10 i - 8 - 20 i )0 = 4 - 8 + 10 i - 20 i0 = - 4 -10 i   0 = 2 ( - 2 - 5 i )0 / 2 = - 2 - 5 i- 2 - 5 i = 0- 5 i = 2i = 2 / - 5
