Answer:
Step-by-step explanation:
Area of a parallelogram = base*height
21*9=189cm^2
5767 ÷ 10,000 = 0.5767
An easier way is to count the zeros in the 10,000 and start on the right and move that many places then place a decimal in the spot you end at.
In this case, we have four zeros so we will start on the right moving to the left four times passing 7 would make it once. passing the 6 would make it twice, then passing the 7 would make it three times and passing 5 would make it four times. Now that we passed it four times We can put a decimal point. " . "
So it would be 0.5767
hope this helped!
Answer:
20
Step-by-step explanation:
Side of the square = hypotenuse of triangle = √(4² + 2²)=√(16 + 4)=√(20)
Area of a square = (side)² = (√20)² = 20 units²
