Question

The length of a rectangle is 2 cm greater than the width. The area is 80 cm. Find the length and width.

Answer 1

let the width by x cm
length= (x+2)cm
area = (x+2) times (x) = 80

Answer 2

fLength 10cm
Width 8 cm
Area = Length x Width
80cm(cubed) = 10cm x 8cm

Answer 3

\[(x+2) \times x = 80\]
\[x ^{2} + 2x-80 = 0\]

Answer 4

solve the equation and get x
