Question

Area of a rhombus is 42 sq cm. one of the diagonals is 11.2 cm find the length of its side.​

Answer 1

Answer:

We know the formula to find the area of rhombus:

Area of Rhombus = 1/2 × diagonal 1 × diagonal 2

42 cm^2 = 1/2 × 11.2 × d2

42 cm^2 = 5.6 × d2

42/5.6 = d2

7.5 = diagonal (2)
