Hi there there's several ways this could be proven one way us to consider the allied angle theory where two angles formed between parallel lines are supplementary which in this case can be proven by
2(45)+90=180⁰ ✔
or 3(45)+45=180⁰✔
this would not be the case if it wasn't parallel
Consequently, you can also use the alternate angle theory where you essentially extend one of the lines and you'll see two equal alternate angles

Answer: 21cm
Step-by-step explanation:
To find the area of a rectangle you just multiply the length by the width. In this case we have 12(width) x ?(length) = 252. To solve we would just divide the area by the known measurement to find the missing one, so 252/12 =21cm
