Hi there!!!
So using this rule:
Area = base * height
20ft * 15ft = 300ft^2
↑ ↑
base height
HOPE IT HELPS U!!!!!!!!!
THE ANSWER IS 300 FT^2

Step-by-step explanation:
B) Surface Area
C) Volume
Answer:
7 9/14
Step-by-step explanation:
The girls ate 8 1/7 of a pie, so we mark G=8 1/7
The boys ate 1/2 of a pie, so we mark B=1/2
The girls ate the more pies, so we do this:
G-B
We plug the G and the B in, and it is 8 1/7-1/2
We change it to the common denominator, which is 14. We have 8 2/14- 7/14
we take a one and add 14 to 2 and we have this:
7 16/14-7/14
and that equals 7 9/14
It is always too 100.0 so one decimal place
You need to add two mixed numerals.
One is positive and one is negative.
To add a positive number and a negative number, first take the absolute value of both, making them both positive. Then subtract the smaller absolute value from the larger absolute value. Finally, the sign of the answer is the same sign as the number that has the larger absolute value.
The numbers are -4 5/8 and 2 1/8
Take absolute values:
|-4 5/8| = 4 5/8
|2 1/8| = 2 1/8
Subtract the smaller absolute value from the larger absolute value.
4 5/8 - 2 1/8 = 2 4/8 = 2 1/2
The greater absolute value is 4 5/8.
Since the number with the larger absolute value was -4 5/8, a negative number, the answer is negative, -2 1/2
-4 5/8 + 2 1/8 = - 2 1/2
