The perimeter is the sum of its 4 sides and its area is length times width
Triangle = sum of its 3 sides Square = sum of its 4 sides Rectangle = sum of its 4 sides
Area in square units = 0.5*(sum of parallel sides)*height
It is the sum of each of the six square faces. Each face has an area of s2 square units where s is the side length. So the total surface area is 6s2 square units.
Any positive value upto 0.36 square units. A 0.6 x 0.6 square will have the maximum area of 0.36 sq units; a 0.5 x 0.7 rectangle will have an area of 0.35 sq units, and the area will be reduced as you reduce one of the measures and increase the other so that their sum remains 1.2 units so that the perimeter is 2.4 units. 0.1x1.1 will be 0.11 sq units 0.01x1.19 will be 0.0119 sq units 0.001x1.199 will be 0.001199 sq units 0.0001x1.1999 will be 0.00011999 sq units, etc.

The sum is 11. The average is 5½. The area of a 3 x 8 rectangle is 24 (square units).
Any positive value upto 36 square units. A 6x6 square will have the maximum area of 36 sq units; a 5x7 rectangle will have an area of 35 sq units, and the area will be reduced as you reduce one of the measures and increase the other so that their sum remains 12 units so that the perimeter is 24 units. 1x11 will be 11 sq units 0.1x11.9 will be 1.19 sq units 0.01x11.99 will be 0.1199 sq units 0.001x11.999 will be 0.011999 sq units, etc.
Triangle = sum of its 3 sides Square = sum of its 4 sides Rectangle = sum of its 4 sides
The perimeter of a square is the sum of the lengths of its sides, while the area is the square of one of its sides. That is, if each side is S units long, then Perimeter = 4*S units and Area = S*S square units.
Its area in square units = 0.5*(sum of parallel sides)*height
Area in square units = 0.5*(sum of parallel sides)*height

Area in square units = 0.5*(sum of parallel sides)*height
Area of a trapezoid in square units = 0.5*(sum of parallel sides)*height Perimeter = sum of its 4 sides
If it was a square, the answer would be 81 square cm. The area will be the product of two numbers whose sum is half the perimeter.
