Answer:

Lanza is correct.

Step-by-step 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.

Answer:

26.75 units²

Step-by-step explanation:

This shape can be split into 3 triangles and a square. Find the area of each shape then add them all up.

$A(Square)=2(2)=4\\\\A(Triangle)=\frac{1}{2}(2)(2)=2\\\\A(Triangle)=\frac{1}{2}(5)(2)=5\\\\A(Triangle)=\frac{1}{2}(9)(3.5)=15.75\\\\A(Shape)=4+2+5+15.75=26.75$

Therefore, the area of the shape is 26.75 units².
