First find the area of the large rectangle which is 90 by you times 3 and 3 which is 9 then you times 5 and 2 which is 10 after that u times 9 and 10 which is 90 So to make the small rectangle times 6 and 15 because 3 times 2 equals 6 and 5 times 3 equals 10 so that means the area of one small rectangle is 6 and the other rectangle us 15 then u multiple
Answer:

Answer:
.
Step-by-step explanation:
Let us for a few seconds nevermind there's a circle at all, so we only really have a triangle by itself.
now, EF = 18, wait a second! EF is the base of the triangle, and h = 10.725, wait a minute!! "h" is the height of the triangle.
so, what's the area of a triangle whose base is 18 and has a height of 10.725? yeap, we knew you'd know that one.
what's the length of the arcEF? well, we know the central angle of ∡FOE is 80°, well, arc's get their angle measurement from the central angle they're in, so if ∡FOE is 80°, so is arcEF then.
