Question

find the area of rhombus with side 5cm and one diagonal is 6 cm​

Answer 1

Answer:

24 cm sq.

Step-by-step explanation:

A = 1/2 × d √4a²-d²   [Formula]

   =1/2 × 6 √4 × 5² - 6²

   = 3 √100 - 36

   = 3 √64

   =3 × 8

    =24 cm sq.

Answer 2

Step-by-step explanation:

Here, side = 5 cm, one diagonal = 6 cm

H²= p²+b²

5²=3²+b²

Here we use 3 because when you draw figure than we take half of 6.

25= 9+B²

B²=25-9

B²=16

B=8

THEN we add 8 double time to find diagonal of other side than 8+8=16

Area = 1/2 * product of diagonals

Area = 1/2*16*6

Area = 48 cm²
