It is: 9+11+9+11 = 40 inches
Perimeter = 100 inches Area = 600 square inches
perimeter is the sum of all side lengths. Since a 9 by 11 has 2 sides 9 inch and 2 sides 11 inch, perimeter is 9+9+11+11 = 40 inches
4 inches x 3 sides = 12 inches for the perimeter.
Perimeter = 12+12+7+7 = 38 inches
34 inches
Find the area of an equilateral triangle that has a perimeter of 21 inches. Round the answer to one decimal place.
To find the perimeter you just add up the sides. So it would be 24 inches.
the perimeter is 3 times as long as the diameter Example: if my diameter is 7 inches long my perimeter is 3 times as much so it is 21 inches long
for area you times the two numbers and for perimeter you add the numbers
A bit of missing wording here?
For any perimeter, the rectangle with the greatest area is a square.For a 16-inch perimeter, the greatest rectangular area is 16 square inches,inside a square with 4-inch sides.But if you don't necessarily need straight sides, then you can squeeze more areainside the same perimeter with a circle. A circle with a 16-inch circumference has anarea of 20.372 square inches.
24 inches You can find the perimeter of a triangle by adding the lengths of all three sides. In this case, since the triangle measures 6, 8, and 10 inches, its perimeter would be the sum of these numbers which is 24 inches.
