c. about $6,500
the difference between two consecutive integers is 2.
thus the difference between the length and the width of the rectangle also differ by 2.
x² – 10x + 12x – 120=0
x(x-10) + 12( x-10)=0
either x-10=0 or x+12=0
x=10 0r -12
we consider positive roots only. thus x=10
width = 10
length = 10+2 =12
answer: 189 sq.ft
plot the coordinates and connect the dotsfind the area of the shape by adding the squares togethermultiply the grid by 9 since each grid is 9 sq.ft
