The point A (p, 4) lies on L1
(a) Find the value of the constant p.
(1)
The line L2
passes through the point C (2, 4) and is perpendicular to L1
(b) Find an equation for L2
giving your answer in the form ax + by + c = 0,
where a, b and c are integers.
(5)
The line L1
and the line L2
intersect at the point D.
(c) Find the coordinates of the point D.
(3)
(d) Show that the length of CD is 3
2
√5
(3)
A point B lies on L1
and the length of AB = 80)
The point E lies on L2
such that the length of the line CDE = 3 times the length of CD.
(e) Find the area of the quadrilateral ACBE.

You need to divide the quadrilateral into two triangles. Find the area of those two triangles and add them together.

Have you drawn a diagram? Draw a big diagram, label all points, then fill in their distances using Pythagoras.
