Five identical rectangles fit
together as shown.
By studying the diagram,
complete the following lines of
algebra.
i) a + b = .
15 cm
(ii) 2b = .
(ii) .. b = .
(iv) .:. a + ( ) = . using (i)
(v) ..a=
(vi) . b =
Hence calculate the total area, in cm2, covered by the rectangles.

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, –6) is rotated 90° counterclockwise. (x, y) → (–y, x) 1. switch the x- and y-coordinates: (6, –3) 2. multiply the new x-coordinate by –1: (6(–1), –3) 3. simplify: (–6, –3) .
