If p=76 inches what is the width? 19 inches height

Question

The perimeter is 76inches the height is 19inches what is the width? 

Answer 1

If the shape is a rectangle, then:

 

Perimeter = 2·Length + 2·Width

76 inches = 2·(19) + 2·Width

76 = 38 + 2·Width

38 = 2·Width

19 inches = Width

 

Since Width = Length = 19 inches,  the shape is a square.
