What is the difference between rhombus and a square?

A rhombus is a quadrilateral containing 2 pairs of parallel sides. All sides are the same length and opposite angles are equal as well.

A square is a special case of a rhombus, where the angles are all 90 degrees.

Every square is a rhombus, but not every rhombus is a square.

A rhombus is a parallelogram. Remember that opposite sides of a parallelogram are always congruent. A rhombus also has two pairs of opposite congruent angles. Angles that are across from each other are congruent.

A square is a type of rectangle. Remember, a square is a type of quadrilateral that has all sides equal. A square has diagonal lengths that are equal but a rhombus does not. Lastly, each of the angles of a square measure 90 degrees but opposite angles are equal for a rhombus.    

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
