Question

The area of a rhombus is 20 cm and the lenght of the altitude is 5 cm then the perimeter will be

Answer 1

Answer: 16cm

Step-by-step explanation:

area of any parallelogram is given by base * height

base = to find let it be x

height = 5 cm

area = 20 cm²

so x*5=20

=> 5x = 20

=> x = 20/5

=> x= 4

in a rhombus all sides are equal

so perimeter = 4x where x is the length of the side

=> perimeter =  4*4 = 16cm
