Answer:
x = 28
Step-by-step explanation:
If the quadrilaterals are similar, there is a proportionality among their sides:
The top side in the large figure (70) is to the top side in the small figure (10) in the same ratio as the left side (x) in the large figure is to the left side in the small figure (4). This in math terms is written as:

We can then solve for the unknown "x" by multiplying both sides by 4:

I could be wrong but I got 28. I devided 420 by 15
It’s £4.5
Convert 25 to a decimal so 0.25
0.25 x 18 = 4.5
