Question

find the area of rhombus whose side is6.5 cm and altitude is 5cm .If one of its diagonal is 13 cm long,find the length of other diagonal.​

Answer 1

Answer:

5 is the answer

Step-by-step explanation:

rhombus is also parallelogram

so its area = 6.5 × 5 = 32.5

now area of rhombus is 1/2 × d1 × d2

32.5 = 1/2 × 13 × d2

d2 = 32.5 × 2 / 13 = 5
