Higher June 2018 Paper 3 Q3
3 Here is a trapezium drawn on a centimetre grid.
On the grid, draw a triangle equal in area to this trapezium. (2)
| Answer | Mark | Mark scheme |
|---|---|---|
| Triangle of area 18 | M1 | for a complete method to find area of trapezium eg \(\dfrac{1}{2}(2 + 7) \times 4\ (= 18)\) OR for a triangle drawn of area 36 OR for a triangle that would give an area ft their area of trapezium |
| A1 | for a triangle drawn of area 18 eg base = 6, height = 6 or base = 9, height = 4 |
Additional guidance
The value for the area of the trapezium must be clear for the ft to be checked.
Accept use of dimensions that are not whole numbers as long as the intention is clear
