Calculate the area of the rhombus shown below if kn = 13.7 and jl = 30.8

area of rhombus is given by:

where p and q are diagonals of rhombus

In a rhombus diagonals bisect each other.

so if KN=13.7

KM = 2KN

KM =2(13.7) = 27.4

Area = 421.96/2=210.98

Answer : Area of rhombus =210.98

or

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒

⇒ ⇒

factorizing, we get that:

  ⇒

then, the solutions are: or

nothing extraneous has been found!

the correct answers i think are b. and d.

give me brainliest if it is correct!
