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.
Answer:
d would be the answer
Step-by-step explanation:
i took the test
The answer is B. 75 because 105 plus 75 equals 180 degrees...... I used to work on this when I was in 6th grade so it is easy to me hope that helped i tried my best hope you get a 100 hundred as your grade
The answer is = B. 75
The absolute value of zero is zero
Maximum speed: 55mph + 5mph = 60mph
minimum speed: 55mph - 5mph = 50mph
Hope this helped?
