Sofie has 13 shapes. There are triangles rectangles and hexagons. 4 shapes have 3 straight sides. Two shapes are hexagons. How many shapes are rectangles

There would be 7 rectangles.

Step-by-step explanation:

Given,

Total shapes = 13,

Since 4 shapes have 3 straight sides,

Also, a shape with three sides is a triangle,

Thus, triangular shapes = 4,

Now, hexagons = 2,

So, remaining shapes = total shapes - triangles - hexagon

= 13 - 4 - 2

= 7

According to the question,

There are only three shapes, triangle, hexagon and rectangle.

Therefore,

Rectangles = remaining shapes = 7.
