# Diamond diagonals

Calculate the diamonds' diagonals lengths if the diamond area is 156 cm square and the side length is 13 cm.

Result

u =  21.633 cm
v =  14.422 cm

#### Solution:

Checkout calculation with our calculator of quadratic equations.

$v = \sqrt{ x_{ 2 } } = \sqrt{ 208 } = 4 \ \sqrt{ 13 } \doteq 14.4222 = 14.422 \ \text{ cm }$
