My working out but i have gone wrong somewhere

Step-by-step explanation:

Simultaneous equations

3C+4t=6.60 x 2

1C+8t=7.20

6c+8t=13.20

1c+8t=7.20                 Subtract

5 Cheese burgers=6

1 cheese burger = 1.20

Substitute

1.20+8t=7.20

8t= 6

taco= 1.34

Your question is calling the figure ABCD, but the image is showing PQRS


Using the letters that you wrote:

Because the figure was only rotated and not scaled , the sides with the same letters would still be the same

So AB would be the same as A'B' ( Length of AB = Length of A′B)

and

BC = B'C'

CD = C'D'

AD = A'D'


Or by the picture:

PQ = P'Q'

QR = Q'R'

RS = R'S'

PS = P'S'
