Which has a greater perimeter a 28 inch square or a 21 inch by 31 inch rectangle?
28 inch square
If the area of a square is forty nine squared what is the perimeter of the square?
The perimeter is 28.
If Perimeter of a rectangle that has a width of x inches and a length of x plus 16 inches is 2x plus 2x plus 16 inches simplify the expression for the perimeter Find the perimeter if x equals 14?
If the rectangle has a width of x inches, and a length of x + 16 inches, then its perimeter equals to 2x + 2x + 32 or 4x + 32. If x = 14, then x + 16 = 30. So the perimeter of rectangle becomes 2(14) + 2(30) = 28 + 60 = 88 inches.
Which number goes into 21 and 28?
When figuring out what number goes both into 21 and 28, you should look at the factor paris. 21: 1 x 21, 3 x 7 28: 1, 28, 2 x 14, 4 x 7 7 goes into both 21 and 28.
What is the perimeter of 7?
If the width is seven on both sides and the length is seven on both sides then the perimeter is 7+7+7+7 = 28.
What times 21 equals 84?
28*21 equals 84
The legs of a right triangle are 21 and 28 inches long What is the area of the triangle?
Area = 0.5*21*28 = 294 square inches
The legs of a right triangle are 21 and 28 inches long respectively. What is the area of the triangle?
Area = 0.5*21*28 = 294 square inches
Is 21 28 35 right triangle?
Yes
What mistake was made in this equation 3x plus 7 equals -4x plus 28 -x plus 7 equals 28 -x equals 21 x equals -21?
3x + 7 = -4x + 28 implies 7x + 7 = 28
What is the answer of 4a-7 equals 21?
21 + 7 = 28 28 / 4 = 7 Your answer is 7.
The legs of a right triangle are 21 and 28 inches long respectively What is the area of the triangle?
294 in^2
The legs of a right triangle are 21 and 28 inches long what is the are of the triangle?
The area is 294 square inches.
The length of the sides of a triangle are consecutive even numbers find the length of the longest side if it is 22 units shorter than the perimeter?
Let the length of the longest side of the triangle be x units.Since the lengths of the sides of the triangle are consecutive even numbers, which differ by 2, the perimeter of the triangle equals to (x - 4) + (x - 2) + x = 3x - 6.Since the length of the longest side is 22 units shorter than the perimeter, the perimeter of the triangle also equals to x + 22. So that3x - 6 = x + 22 (subtract x and add 6 to both sides)3x - x + 6 - 6 = x - x + 6 + 222x = 28 (divide both sides by 2)x = 14Thus the longest side has a length of 14 units.
What is 3a-7 equals -28?
3a - 7 = -28 Therefore, 3a = -21 a = -21/3 Therefore, a = -7
What is perimeter of a square with 7 cm sides equals to?
