Question

The area of a rhombus is 65 square units. The length of one diagonal is 13 units. What is the length of the other diagonal? 5 units 6 units 10 units 12 units

Answer 1

10

Explanation:

Answer 2

The length of the other diagonal is 10 units

Explanation:

we know that

The area of a Rhombus is equal to

`A=(1)/(2)[D1D2]`

where

D1 and D2 are the diagonals of the rhombus

we have

`A=65\ units^(2)`

`D1=13\ units`

substitute in the formula and solve for D2

`65=(1)/(2)[(13)D2]`

`130=[(13)D2]`

`D2=130/13=10\ units`
