13 Milo is trying to find the area of this rectangle.
He writes,
“The area is 400 cm2 because \(5 \times 4 \times 5 \times 4 = 400\)”
(a) Explain what is wrong with Milo’s method. (1)
Anya works out the area of a shape.
Her answer is 86 cm.
(b) Explain why her answer cannot be fully correct. (1)

|---|---|---|
| Explanation | C1 | for correct explanation Acceptable response should have multiplied 5 and 4 (once) it should be (just) \(5 \times 4\) it is \(b \times h\) or \(l \times w\) she has not used the formula for area it should be 20 (cm2) shouldn’t multiply all (four) sides Not acceptable response he has found the area twice he is correct he has worked out volume he has worked out the perimeter or he should have added the 4 sides |

Units may be ignored
| Answer | Mark | Mark scheme |
