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
you would add the topp and the side then times it by two i think
For a rectanglar picture, measure the length and width of the space where the picture will fit inside the frame and multiply the two measurements together to obtain the area. Example: 7 inches x 9 inches = 63 square inches. For a circular picture, measure the diameter of the space where the picture will fit inside the frame then multiply the radius (half the diameter) by itself and by pi (3.14). Example: for 6 inch diameter, 3.14 x 3 inch x 3 inch = 28.26 square 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 of a triangle, add the three sides. Perimeter = 6in + 8in + 10in = 24in.
Perimeter = 100 inches Area = 600 square inches
It is: 9+11+9+11 = 40 inches
you would add the topp and the side then times it by two i think
4 inches x 3 sides = 12 inches for the perimeter.
Perimeter = 12+12+7+7 = 38 inches
The frame is 1 cm wide.

34 inches
look it up
The frame is 14 cm wide
it would be 68.5 inches
