Rhombus A2p

The rhombus area is 13 cm2, and its height is 5cm long. Find the perimeter of this rhombus.

Correct answer:

x =  10.4 cm

Step-by-step explanation:


5a = 13
x = 4a

5·a = 13
x = 4·a

5a = 13
4a-x = 0

Row 2 - 4/5 · Row 1 → Row 2
5a = 13
-x = -10.4


x = -10.4/-1 = 10.4
a = 13/5 = 2.6

a = 13/5 = 2.6
x = 52/5 = 10.4

Our linear equations calculator calculates it.
