the dimensions of a rectangle are so that the length is 9 in more than its width. if the length was doubled and the width was decreased by 4 in, the area would be increased by 110 in ^2. What are the length and the width of the rectangle?

Question

gorv · Answer

let width=x

gorv · Answer

length=x+9
area=x(x+9)

anonymous · Answer

Area = Length x Width  First rectangle A = 9 x. x  Second rectangle A + 110 = (2x(9 x)) . (x-4 )

gorv · Answer

length is doubled=2*(x+9)
width after decrement=x-4
new area=2*(x+9)*(x-4)
new area - old area=110
now solve it
