Best Answer

Perimeter is the distance around the figure. Add all sides.

Area depends on the figure. Triangle --- 1/2 bh

Rectangle --- lw. Others --- divide into triangles and find the area of each triangle then add all together.

Which mathematician invented the formula for perimeter?

Although some have said Archimedes, my opinion is that the formulas for area and perimeter of a rectangle were well known before his time (300BC). The Babylonians in 1500BC knew how to create Pythagorean triples, so I wouldn't be surprised if they knew this. Archimedes did discover more difficult formulas, such as perimeter and area of a circle, and volume of a sphere and a cone.

What shape has an area of 12 and a perimeter of 16?

The shape that has an area of 12 and a perimeter of 16 is a rectangle. To find the dimensions of the rectangle, you can set up equations using the formulas for area and perimeter. Let the length of the rectangle be L and the width be W. The equations would be: 2L + 2W = 16 (perimeter) and LW = 12 (area). Solving these equations simultaneously will give you the dimensions of the rectangle.
