Solution: A rhombus abcd whose area is 72 square units.
Diagonals ac and bd intersect each other at point e.
Also, db= x-1,
ec = 8 units, so, ac=16 units → as diagonals of rhombus bisect each other.
→Area of Rhombus = 1/2 × Product of Diagonals
→ 72 = 1/2×16×(x-1)
→144= 16 (x-1)
Dividing both sides by 16,we get
→ x-1=9
→ x=9+1
→ x=10 units

<h3><u>MEAN</u></h3>
Mean is the average. To find the mean of a data set, you have to add all the numbers and divide the sum by the amount of numbers you added.
<em>In this equation, you have 8 numbers. That means you will be dividing by 8. </em>
The first thing you need to do is add all the numbers. Add:
Now that you have added all the numbers and got the sum, divide by 8. Remember that you will be dividing by 8 since you added 8 numbers.
Divide:
The mean is 66
