More information is needed to answer you.
Here,
let width(b)be x then,
length (l)=9cm+x
area =112 sq cm
now,
area of rectangle=l*b
or, 112=(9+x)x
or, 112=9x+x^2
or, 0=x^2+9x-112
or, 0=x^2+(16-7)x-112
or, 0=x^2+16x-7x-112
or, 0=x(x+16)-7(x+16)
or, 0=(x-7)(x+16)
either,
0=x-7
or,7=x
x=7cm
Or,
0=x+16
or, -16=x
x= -16[impossible,as distance is never negative] so,
x=7cm
therefore,length = 7cm + 9 cm = 16cm and width = 7cm.

Answer:
No
Step-by-step explanation:
29/100 can be written as 0.29 , not 0.029.
Answer:
midpoint = (5,7)
Step-by-step explanation:
Use the midpoint equations. x1 + x2 / 2 and y1 + y2 / 2
2 + 8 = 10/2 = 5
10 + 4 = 14/2 = 7
