Question

the area of rhombus is 28 metre square one of its diagonal 4 cm find the length of other diagonal

​

Answer 1

Answer:

A= 28m

formula = 1/2 product of diagonal

Step-by-step explanation:

so

28 = 1/2* 4*X

28 = 2X

X = 14

so diagonal = 14

Answer 2

SOLUTION -

GIVEN -
Area of rhombus = 28 m = 2800 cm .
Length of its diagonal = 4 cm .

Length of other diagonal ?

AREA OF RHOMBUS =  1/2 x d1 x d2
                         2800 =  1/2 x 4 x d2
                              d2 = 1400 cm

THEREFORE THE LENGTH OF OTHER DIAGONAL IS 1400 cm or 14 metre .
