If KM is drawn on this quadrilateral, what will be its length ???
2 answers:
Answer:
B. 18
Step-by-step explanation:
We have been given an image of a quadrilateral and we are asked to find the length of segment KM.
We can see from our given quadrilateral that its two sides are parallel that is KL||JM.
We can also see that its two opposite sides are equal that is .
Since we know that an equilateral trapezoid has parallel bases and equal opposite sides or legs, therefore, our given quadrilateral is an equilateral trapezoid.
Since diagonals of equilateral trapezoid are congruent, therefore, the length of KM is 18 units and option B is the correct choice.

Answer:
16 Unit
Step-by-step explanation:
With P(-2,1) , Q(6,1) , R(4,-3) , S(4,1) , the triangle and its altitude look like the one attached in figure.
The length of base PQ is the difference in the x-coordinates of P and Q,
6-(-2)=6+2=8 , because the y-coordinates are both the same as 1.
The height (the length of altitude RS is the difference in the y-coordinates of R and S,
1-(-3)=1+3=4 , because the y-coordinates are both the same as 4 .
The area is
