Answer:
63 sq ft
Step-by-step explanation:
The formula for the area of a trapezoid is
A = h(a + b)/2 where a and b are the lengths of the parallel sides and h is the distance between them
A = 7(11 + 7)/2
= 7(18)/2
= 63 sq ft
Answer:
i need a set of numbers to do this
Step-by-step explanation:
I got it now!
(hold your applause)
Area of the rectangle is 12 to the power of 2 (or you can just say squared) and that equals 144cm squared
the area of the circle is pi radius squared (in this case radius is 3) and it equals 9 pi squared
to get the shaded area that is last over with the circles removed you would have to do (144)-(9pi) (this part is unachievable without a calculator that has the pi symbol to fill in instead of just writing 3.14) and after you get the answer of that which is 115.725666118
and that amount you must do the same with so it would be
(115.725666118)-(9pi) and that equals ...............
87.4513322357
