Question

. The perimeter of the rhombus is 20 cm and the altitude is 4.8 cm. If the length of one
diagonal is 6 cm, find the length of the other diagonal.​

Answer 1

Answer:

Step-by-step explanation:

perimeter of rhombus is 20cm

that is  4 * side = 20

          therefore side is 20/4 = 5cm.

now 1/2 * base * height = area

    1/2 * 5 * 48/10 = 12cm square.

now area of rhombus = 12

1/2 * d1 * d2 = 12

1/2 * 6 * d2 = 12

3d2 = 12

therefore d2 = 4cm
