Question

The area of the rhombus is 90cm. If is perimeter is 56cm find the b of the diagonal

Answer 1

In a rhombus we know that all sides are equal in length.

Perimeter = 4*side length

56 = 4*side length.

Side length = 56/4

                     =14 cm

Area of rhombus = altitude×base

90 = 14× alt.

Alt. = 6.42 cm

which is the diagonal of the rhombus.
