Answer to Problem 17PSB
The perimeter of JKMO is
Explanation of Solution
Given information : The following information has been given
EFGH is a rectangle
J,K,M and O are midpoints
Formula used : Pythagoras theorem states that sides of a right
Calculation : We know that JKMO are the midpoints of the rectangle. Thus, we know that
Now, we know that diagonals of a rectangle are equal due to Pythagoras theorem mentioned above. Thus, we can say that
Now, substituting the value of FH, we get
Thus, the value of perimeter is
b
The most descriptive name for JKMO is to be given
b
Answer to Problem 17PSB
The most descriptive name for JKMO is Rhombus
Explanation of Solution
Given information : The following information has been given
EFGH is a rectangle
J,K,M and O are midpoints
As we know by Pythagoras theorem in the first part that all sides of JKMO are equal, we can say that the name Rhombus best suits any quadrilateral with four equal sides, when opposite sides are known to be parallel.
