Question

In rectangle KLMN, KM =6x + 16, and LM =49. find the value of x

Answer 1

The rectangle is a figure with opposite sites equal in length.
Also, the diagonals in a rectangle have equal length.
KM and LN are the diagonals and they are equal by definition.
So, we can write the equation: KM=LM
6x+16=49
6x=49-16
6x=33
x=5.5
