Answer:
Lanza is correct.
Explanation:
The two missing dimensions on the left are 4.5 m on the vertical line, and 5 m on the horizontal line.
These dimensions let us partition the garden a number of ways. One way is ...
- a rectangle 9 m by 4.5 m
- a rectangle 4 m by 3.5 m
The total of the areas of these is ...
(9)(4.5) +4(3.5) = 40.5 +14 = 54.5 . . . . square meters
At £16 per square meter, Lanza's charge will be ...
£16 × 54.5 = £872
Lanza is correct that she will have to charge more than £800.
