The area of rhombus is 35 square feet the length of one of the diagonals is 10 feet what is the length of the other diagonal

Area of a rhombus =

Given are:

Area = 35 square feet

Length of diagonal = 10 feet

Let the diagonal whose length is to be found be 'B'

So the length of the other diagonal =

So, the length of the other diagonal is 7 feet.

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!

option b  

step-by-step explanation:

we know that

the distance from point n to lm in the figure is equal to the distance of the perpendicular line to lm that passes through the point n

so

the distance is equal to the segment no

> given problem

therefore

the distance from point n to lm is equal to
