Answer:

The answer is 27.5 units.

Step-by-step explanation:

The shape looks like trapezoid which corners are at below points:

A(-3,3)

B(-3,-4)

C(2,-2)

D(2,2)

To calculate surface of this trapezoid, we can use the formula below:

S=(CD+AB)*h/2

Where:

CD=4 unit

AB=7 unit

h=5 unit

S=(4+7)*5/2=27.5

Answer:

1) £2 = €2.32

£5 = €5.80

£50 = €58

2) The graph will be a straight line

3) (0, 0)

4) Label the independent variable, £ on the x-axis and dependent variable € on the y-axis

Step-by-step explanation:

1) The given conversion factors is £1 = €1.16

Therefore;

£2 = 2 × €1.16 = €2.32

£2 = €2.32

£5 = 5 × €1.16 = €5.80

£5 = €5.80

£50 = 50 × €1.16 = €58

£50 = €58

2) The shape of the plot of the directly proportional currencies graph will be a straight line

3) Given that the £ is directly proportional to the € and that the value of the € can be found directly by multiplying the amount in £ by 1.16, without the addition of a constant, the graph crosses the axes at the origin (0, 0)

4) The y-axes which is the dependent variable should be labelled €, while the x-axis which is the independent variable should be labelled £
