Answer:
24 cm²
Step-by-step explanation:
To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...
P = 2(AB +BC)
BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm
Then CD is ...
CD = BD -BC = 9 cm -4 cm = 5 cm
The area of the trapezium is given by the formula ...
A = (1/2)(b1 +b2)h
A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²
The area of trapezium CDEF is 24 cm².
8pi ft
Just divide 16 by 2 because it’s half of the diameter
I don’t see the image can you please add one to the comments so I can answer it. Thanks
The answer is A. :). Have a great day!
If you travel 300miles in 5h then you travelled 60miles per hour.
Hence in 7h you can travel 7*60=420miles
