1 A rectangular picture frame has perimeter 70 cm.
a The width of the frame is x cm. Find an
expression, in terms of x, for the height
of the frame.
b Find an equation for the area of the
frame, Acm2, in terms of x.
C Plot the graph which shows how A
varies with x. Use a suitable domain and
range. Hence sketch the graph on paper
d Find the x-intercepts of the graph in part
e State what these two values of x represer
f Hence find the equation of the graph's
line of symmetry, and state what this
tells you in the context of the problem
