Answer:
192 
Step-by-step explanation:
We use the same area equation for a rectangle
A = b * l
A = 12 * 16
A = 192
Answer:
X=135 degrees
Step-by-step explanation:
the total interior angle of a triangle is 180.
To work this out you would first add the interior angles of B which is 69 and the interior angle of C which is 66, which gives you 135.
The next step is to minus 135 from 180, which gives you 45. This is because the total interior angle of a triangle is 180.
Then to work out the angle of x you would minus 45 from `180, which gives you 135. This is because the total angle in a straight line is 180 degrees.
1) Add the angles of 69 and 66.

2) Minus 135 from 180.

3) Minus 180 from 45.

Answer:
It is always important to go through the given problem first to get a concept of the requiremement. Then all the information's available from the question has to be noted down in such a manner that there would be no need to look at the question while solving.
Total number of students wearing jeans = 10
Total number of students wearing shorts = 9
Total number of students wearing capris = 2
Then the total number of students surveyed by Mrs Lane = (10 + 9 + 2)
= 21
Now percentage of students wearing shorts = (9/21) * 100
= (3/7) * 100
= 300/7
= 42.85 percent
So a total percentage of 42.85% of the students were wearing shorts.
