Answer 2

Answer: 16 cm ( Figure attached!)

Step-by-step explanation:

Given perimeter of the rhombus = 40cm

⇒side = 40/4= 10cm ( Sides of a rhombus are equal in length)

Given the distance between the parallel sides ( Height) = 5.6cm

Since Rhombus is a trapezium,

Its area = 1/2 × sum of the parallel sides × height

            = 1/2 ×(10+ 10) × 5.6 = 10 × 5.6= 56$cm^{2}$

Now area of Rhombus = 1/2 × Diagonal 1 ×Diagonal 2

               ⇒ 56 = 1/2 × 7 × Diagonal 2

              ⇒$\frac{56 X 2}{7}$ = Diagonal 2

          Diagonal 2 = 16 cm
