### How do you draw a shape that is in square units but has the perimeter of 7?

All shapes have areas that are in square units so there is nothing
you need do there. So all you need is a closed shape with a
perimeter of 7 units.

### What is the surface area formula for surface area of a prism?

The answer depends on the shape of the prism.
If the prism has bases that are polygons with area B square
units and perimeter P units, and if theprism is L units long, then
the total surface area = 2B + PL square units.

### What is the are of a shape when the perimeter is 42.5?

A perimeter is not enough to determine the area. It depends on
the shape.
The shape has the greatest area if it is a circle and then the
area will be 143.73 square units (approx).
If it a square, the area will be 112.890625 sq units.
But the area can be reduced, without limit, by making the shape
longer and thinner. For example,
20*1.25 rectangle: area = 25 sq units
21*0.25 rectangle: area = 5.25 sq units
21.2*0.05 rectangle: area = 1.06 sq units
21.24*0.001 rectangle: area = 0.2124 sq units
