Surface area of regular polygon with number and length of sides known is:
s2 / A = 4/n * tan 180/n
where s = length of side and n = number of sides
so
9/A = 4/5 * tan 180/5
9/A = 4/5 * tan 36
9/A = 0.58123
A = 9/0.58123 = 15.4843 sq. inches
A square has 4 equal sides and a pentagon has 5 sides and there sides can be of any lengths.
The surface area of a 1 inch cube is: 6 square inches.
The surface area is 13.5 square inches.
the surface area = 22 sq. inches
Entire surface area: 6*8*8 = 384 square inches
A pentagon is a 5-sided figure, and the perimeter is the sum of the lengths of all the sides. A pentagon with 15-inch sides, will have 5 x 15 inches = 75 inches as its perimeter.
Carpenters use geometry for angles and diagonal lengths, area and surface area for walls and sheathing, and the engineering computation of loads per square inch.
A square has 4 equal sides and a pentagon has 5 sides and there sides can be of any lengths.
The surface area of a 1 inch cube is: 6 square inches.
The surface area is 13.5 square inches.
