Question
The figure shows a rectangle ABCD with dimensions 8 cm x 6 cm. A corner is cut off along EF such that BE = CF = x cm. If the length of EF is 60% of the length of diagonal BD, 21. 8 cm 6 cm F (a) express the length of EF in terms of x, +Xcm (b) find the possible lengths of BE. (Leave your answers in surd form.) B x cm E In the figure, a book AB leans against a bookshelf. It is given that AB = 20 cm and BO = 12 cm. If A is lowered by x cm to A' so that B 22. x cm slides the same distance to B', find the value of x. 20 cm O. X cm 12 cm On a football field, a boy runs due east from point P to point Q, and then runs north to point R. The total distance he has travelled is 92 m. If PR=68 m, find the possible distances between P and Q. 23.
