Question

The area of rhombus ABCD is 72 square units. EC = 8 units and DB = x – 1.

What is the value of x?

9
10
14
16

Answer 1

10

Explanation:

Answer 2

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
