The area of a trapezoid is given by:
From the diagram, the bases are 17m 23m, and the the height is 12m.
We substitute the values into the formula to get:
This implies that
Answer:
B.6
Step-by-step explanation:
When we add and subtract, we do it from left to right
13+ (-12) - (-5)
13+-12
13-12 = 1
1 - -5
A negative negative is a positive
1 +5
6
Answer:
Total Number of lines will be 28
Step-by-step explanation:
We can use combinations to solve this question.
Let the two Collinear points be denoted by A and B and the other other points be denoted by x1,x2,x3,x4, x5 and x6.
Suppose that only A and B are collinear.
The number of lines determined by any two of x1 to x6 are given by 6C2= 15
The number of lines from A or B and x1---x6 is given by 6C1 * 2C1= 12
The number of lines from A to B is 1.
Total Number of lines = 15+ 12+ 1= 28
