Answer:
42cm²
Step-by-step explanation:
because if the perimeter of the rectangle is 28 then the length is 5, 5 - 11 = 6, the formula for finding the trapezium is to add the 2 parallel sides, half them, then times them with the length so your sum will look like this, 5+9=14, (i knew the other side was 9 as the length of AB is the same as the length of FC, which is the one of the parallel sides of the trapezium) then we do 14÷2=7, finally we times 7 by 6 which is 42cm²
Answer:
Formula: (x^2 -h) +(y^2 -k)=r^2
The number on the right side of the = is the radius of the circle squared.
(h,k) is the center of the circle.
Hello!
OK, so we need to find out 20 km = ? dam
What we know:
1 km = 100 dam
Now, lets multiply to get our answer:
20 × 100 = 2,000
This tells us that 20 km = 2,000 dam
Check:
2,000 ÷ 20 = 10
This tells us that we are CORRECT!
Answer: 20 km = 2,000 dam
Hope this helps! Good luck! (:
