If it's a rectangle then:- Area = 15*12 = 180 square units Perimeter = 15+15+12+12 = 54 units of measurement
70 inches.
12 inches
To find the perimeter of any polygon just add the length of everyside. In this case you have 4 sides with a length of 12 in. so 12 + 12 + 12 + 12 = perimeter. or to simplify 4 * 12 = perimeter.
The perimeter of a rectangle = 2 x (length + width) = 2 x (12 + 8) = 2 x 20 = 40 inches
Its perimeter: 12+14+12+14 = 52 inches
Perimeter = 4*12 = 48 inches
The perimeter would be 36 inches.
Perimeter = 12+12+7+7 = 38 inches
A rectangle measuring 12 inches by 8 inches has a perimeter of 40 inches, since 12 + 12 + 8 + 8 = 40 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.
The perimeter of the triangle is: 13+12+5 = 30 inches
12+12+15+15=54
Perimeter = distance around all 4 sides = 12 + 5 + 12 + 5 = 34 inches.
12*6 = 72 inches.
The perimeter of a triangle is the sum of the lengths of its sides. In this case, the perimeter of the triangle with sides measuring 3 inches, 5 inches, and 7 inches is 3 + 5 + 7 = 15 inches.
840 in (12 x 2 x (20 + 15))
