The area of rectangle ABCD is 28 cm^2 a) What is the length of side AB in terms of x?
6 cm
length of AB =
(1)
b) If the area of rectangle ABCD is 28 cm^2, we can show that x^2 + ax = b where
a and b are integer values.
Work out the values of a and b.
a=
(1)
b =
(1)

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
