You need to find the length of A F and BC first
Lets call BC --> 'x'
Lets form an equation
9 + 9 + x + x = 28
18 + 2x = 28
- 18
2x = 10
/ 2
x = 5
So now we have the length BC
We can subtract this length from the 11cm to find the vertical height of the trapezium
11 - 5 = 6
Now we have all we need to work it out.
area = (a + b) / 2 x h
area = (5 + 9) / 2 x 6
area = 42 cm^2
Have A Nice Day ❤

Answer:
8, 16, 64
Step-by-step explanation:
8 = 2^3 . . . a perfect cube
16 = 4^2 . . . a perfect square
32 = 2^5 . . . neither a cube nor a square
64 = 2^6 = 4^3 = 8^2 . . . both a perfect cube and a perfect square
128 = 2^7 . . . neither a cube nor a square
Answer:
C) Z
Step-by-step explanation:
In the right triangle, X and Y are side lengths, while Z is the hypotenuse, so C is the correct answer.
Answer:
Either <em><u>10 times</u></em> or <u><em>598,000.</em></u>
Step-by-step explanation:
6 x 10 ^ 5 = 600,000
2 x 10 ^ 3 = 2,000
If we are figuring out the exact number, 600,000 - 2,000. If we are finding out how many powers larger, count.
600,000 - 2,000 = 598,000
600,000 is 10 times larger than 2,000.
See?
600,0<u>00</u>
2,000
