RHOMBUS

RHOMBUS

- a quadrilateral with all sides equal and no 90⁰ angle.

 Illustration:

where:

a = b = c = d

Formula for Area:

A = ( x*y ) / 2

where:

A = area

x = one diagonal of the rhombus

y = other diagonal of the rhombus

Problem:

1. One diagonal side of a rhombus measures 14 inches and the other is 20 inches. Find the area of the rhombus.

Given:

x = 14 in. ( or use y )
y = 20 in. ( or use x )

Required: Area

Solution:

A = ( x*y ) / 2

   = ( 14 in * 20 in ) / 2

   = 280 square inches; final answer
