Area of a Trapezium
The trapezium has two parallel sides and two non-parallel sides
Since sides of lengths 7, 5 are parallel and perpendicular to the side of length 4. Thus the trapezium has bases b1=7, b2=5, and height h=4.
The formula to calculate the area of a trapezium is:
Substituting:
The area of the shaded region is 24 square units
Answer:
7.2 x 10 CUBED
Step-by-step explanation:
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 7,200
New Number: 7.200
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 7 . 2 0 0
Decimal Count: 1 2 3
There are 3 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 7.2 (Please notice any zeroes on the end have been removed)
b = 3
Now the whole thing:
7.2 x 103
Step 4
Check your work:
103 = 1,000 x 7.2 = 7,200
It would be 35 yards (22+13=35 yards) 1+2=3 feet
I did this excat problem in school but my teacher just gave us the answer which is X<2
