Diagram NOT accurately drawn
\(ABDE\) is a rectangle.
\(ED\) is 8 cm.
\(BDC\) is a right-angled triangle.
\(BC\) is 4.5 cm.
\(ABC\) is a straight line.
The area of the rectangle \(ABDE\) is 40 cm2.
Work out the area of the triangle \(BDC\). (3)
| Answer | Mark | Notes |
|---|---|---|
| 11.25 | 3 | M1 for \(40 \div 8\) (= 5) M1 (dep) for finding the area of the triangle eg \(\text{``}5\text{''} \times 4.5 \div 2\) A1 cao |
