In order for the parallelogram to be a rhombus x=?

For a parallelogram to be equal, the lengths of all the sides have to be the same. ... Opposite angles of both rhombuses and parallelograms are equal and co-interior angles of both sum to 180° , but the size of the angles is not affected by the lengths of the sides between them.

3x - 11 = x + 23

3x - x = 23 + 11

2x = 34

x = 34/2

x = 17

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
