Answer 1

Answer:

Ok, so I hope I understood the task. Here goes nothing

Step-by-step explanation:

So, first we calculate the area of the big rectangle,

(√63+√28)*√45 = 15√35

Then we calculate the area of the small rectangle

√7*√5 = √35

Then we do this to get the area left

15√35 - √35 = 14√35

Then we take

$14 \sqrt{35 } \div 15 \sqrt{35} = \frac{14}{15}$

That should explain it
