15 A garden is in the shape of a rectangle 90 m by 60 m.
Flowers are grown in 40% of the garden.
The rest of the garden is grass.
Work out the area of the garden that is grass. (4)
| Answer | Mark | Mark scheme |
|---|---|---|
| 3240 | P1 | for \(90 \times 60\ (= 5400)\) OR \(40 \div 100 \times 90\ (= 36)\) OR \(40 \div 100 \times 60\ (= 24)\) |
| P1 | for a process to work out area that is flowers eg. \(40 \div 100 \times \text{``}5400\text{''}\ (= 2160)\) OR \(\text{``}36\text{''} \times 60\ (= 2160)\) OR \(90 \times \text{``}24\text{''}\ (= 2160)\) | |
| P1 | for a full process to find the area that is grass eg. \(\text{``}5400\text{''} - \text{``}2160\text{''}\ (=3240)\) | |

| ALTERNATIVE | P1 | for \(100 - 40\ (= 60)\) |
| P1 | (indep) for \(90 \times 60\ (=5400)\) OR \(90 \times 60 \div 100\ (= 54)\) or \(60 \times 60 \div 100\ (= 36)\) | |
| P1 | for a full process to find the area that is grass eg. \(\text{``}60\text{''} \div 100 \times \text{``}5400\text{''}\ (=3240)\) OR \(\text{``}54\text{''} \times 60\ (= 3240)\) or \(\text{``}36\text{''} \times 90\ (= 3240)\) | |
