What is the perimeter of a square with a side measuring eleven and a half inches?

Perimeter = 2*(L + W) = 2*(12 + 10.5) = 2*22.5 = 45 inches. Area = 12*10.5 = 126 square inches.

Half perimeter = 109. Subtract 87 and half the answer 22/2 = 11, this is the width. Add on the 87 giving 98, this is the length.

Do-it-in-your-head method:Length + width is half the perimeter, ie 76 inches;76 - 36 = 40;Half of 40 is 20: this is the width;20 + 36 = 56: this is the length.Job done.

Do-it-in-your-head method: Length + width equals half the perimeter, ie 106; 106 - 8 = 98; half of 98 is 49 which is the width, making the length 57.

What is the perimeter of a square with a side measuring eleven and a half inches?

Length + width = half perimeter = 100". Length is 98", width is 2"

Length + width = half of perimeter = 37 in. 37 - 9 = 28, half of 28 = 14 which is the width, and the length is 23

Perimeter = 2*(L + W) = 2*(12 + 10.5) = 2*22.5 = 45 inches. Area = 12*10.5 = 126 square inches.

169 square inches. Folding the square in half leaves 2 edges of the original side length and two of half the side length. Therefore: perimeter = side + 1/2 side + side + 1/2 side = 3 sides ⇒ 3 sides = 39 inches ⇒ 1 side = 39 inches ÷ 3 = 13 inches ⇒ area_original_square = 13 inches x 13 inches = 169 square inches.

Half perimeter = 109. Subtract 87 and half the answer 22/2 = 11, this is the width. Add on the 87 giving 98, this is the length.

Do-it-in-your-head method: 1. Length + width is half the perimeter ie 116 in 2. 116 minus 68 is 48, half of 48 is 24 which is the width, making the length 92 in

Do-it-in-your-head method:Length + width is half the perimeter, ie 76 inches;76 - 36 = 40;Half of 40 is 20: this is the width;20 + 36 = 56: this is the length.Job done.

Length + width = half of perimeter ie 36.7 in. If length is 4.7 in then width is 32 in.

If the area is a square, 1/4 of the perimeter is the length of one side. That length squared is the area. The area will be the product of two numbers whose sum is half the perimeter.

Do-it-in-your-head method: Length + width equals half the perimeter, ie 106; 106 - 8 = 98; half of 98 is 49 which is the width, making the length 57.

perimeter 24 so length + width half of that ie 12. Length 3 times width must be 9 and width 3.
