Calculate the side length of a rhombus if its perimeter is 14.8 dm.

Given:

rhombus ABCE,

P ABCE = 14.8 dm.

Find: AB, BC, CE, EA

Solution:

Consider a rhombus ABCE. In a rhombus, all sides have the same length, that is, AB = BC = CE = EA.

The perimeter of a rhombus is the sum of the lengths of all its sides.

P ABCE = AB + BC + CE + EA;

AB = BC = CE = EA = P ABCE: 4;

AB = BC = CE = EA = 14.8: 4;

AB = BC = CE = EA = 3.7 dm.

Answer: 3.7 dm; 3.7 dm; 3.7 dm; 3.7 dm.
