  2. 2
    A tiler is calculating areas of a parallelogram-shaped tile (base 15 cm, height 8 cm) and a trapezium-shaped tile for a mosaic pattern.
    (a)
    A parallelogram-shaped tile has base 15 cm and perpendicular height 8 cm. Find its area.
    [2 marks]
    (b)
    A trapezium-shaped tile has parallel sides of length 10 cm and 14 cm, and a perpendicular height of 6 cm. Find its area, using Area=12(a+b)h\text{Area} = \frac{1}{2}(a+b)h.

    A builder is calculating the floor area and skirting board length needed for an L-shaped room, formed from a 9 m by 6 m rectangle with a 3 m by 2 m rectangular corner removed.
    (a)
    A room floor is an L-shape formed from a large rectangle 9 m by 6 m with a smaller rectangular corner of 3 m by 2 m removed. Calculate the area of the L-shaped floor.
    [3 marks]
    (b)
    Skirting board is needed around the full perimeter of the L-shaped floor. Calculate the total perimeter of the room.

    A civil engineer is designing a car park as a compound shape: a rectangle 40 m by 25 m, with a semicircular section of diameter 25 m attached to one of the 25 m ends, and a small triangular flower bed cut from one corner.
    (a)
    A car park is a compound shape made from a rectangle measuring 40 m by 25 m, with a semicircular section of diameter 25 m attached to one of the 25 m ends. Calculate the area of the rectangular section, and the area of the semicircular section (use π=3.142\pi = 3.142).
    [4 marks]
    (b)
    A triangular flower bed with base 5 m and height 4 m is cut from one corner of the rectangular section. Calculate the total area of the car park (rectangle plus semicircle, minus the triangular flower bed), giving your answer to 1 decimal place.
    [4 marks]
    (c)
    The car park's total area (from part (b)) needs to be converted for a report requiring the answer in cm2^2. Convert 1235.51235.5 m2^2 to cm2^2, showing your conversion factor clearly.
