6 Here is a rectangle.
The length of the rectangle is 7 cm longer than the width of the rectangle.
4 of these rectangles are used to make this 8-sided shape.
The perimeter of the 8-sided shape is 70 cm.
Work out the area of the 8-sided shape. (5)
| Answer | Mark | Notes |
|---|---|---|
| 147 | P1 | starts process, eg uses \(x\) and \(x + 7\) |
| P1 | starts to work with at least 6 correct sides, may be on the diagram or in an expression | |
| P1 | (dep on previous P1) gives a correct expression for the perimeter, eg \(x + x + 7 + x + 7 + x + 7 + x + x + 7 + x + 7 + x + 7\) or adds at least 6 correct sides and equates to 70 | |
| A1 | for width = 3.5 oe and length = 10.5 oe | |
| B1 | ft (dep P2) for correct area for their \(x\) |
