If one side of a rhombus has endpoints (...

If one side of a rhombus has endpoints (4, 5) and (1, 1), then the maximum area of the rhombus is

A

A. 50 sq.units

B

B. 25 sq.units

C

C. 30 sq.units

D

D. 20 sq.units

Text Solution

Verified by Experts

The correct Answer is:
B
From the figure Area of a rhombus `=2xx("Area of"Delta ABD)`
`=2xx(1)/(2)xx5xx5sintheta`
`=25sintheta`
Hence,the maximum area is 25 (when `sintheta=1`).
