If 10 and 11 are its diagonals then its area is: 0.5*10*11 = 55 square units
To find the area of rectangle ABCD, you can multiply the length and the width. Since the diagonal divides the rectangle into two congruent right triangles, you can use the Pythagorean theorem to find the length of ABCD. Letting x represent the length, you can solve for x: x^2 + 11^2 = 18^2, which simplifies to x^2 = 225. Thus, x = 15. The area of the rectangle is 15 * 11 = 165 square units. To find the perimeter, you can add all four sides together: 15 + 11 + 15 + 11 = 52 units.
No, it equals 9, but XI equals 11.
X=5Y= 92x + 11= ?2(5)+11=?10+11= 21
The number that equals 121 when squared is 11.

The 2 lengths that you described are diagonals. The area of a rhombus when you know the diagonals is half the product of the diagonalsIn your case, that's 14 x 17 / 2 = 119
The diagonals of a rhombus are perpendicular to each other and bisect one another. So you can consider the diagonals dividing the rhombus into 4 identical, right-angled triangles where the sides subtending the right angle are of length 10/2 and 11/2. The area of each of these triangles is 1/2 * 10/2 * 11/2 = 110/8 There are 4 such triangles, so their combined area is 4 * 110 / 8 = 110 / 2 = 55 square units.
If 10 and 11 are its diagonals then its area is: 0.5*10*11 = 55 square units
If those are its diagonals then area is: 0.5*10*11 = 55 square units other wise use Pythagoras to find diagonal EG because area of a rhombus is 0.5 times the product of its diagonals.
A triangle with side a: 5, side b: 8, and side c: 11 units has an area of 18.33 square units.
To find the area of rectangle ABCD, you can multiply the length and the width. Since the diagonal divides the rectangle into two congruent right triangles, you can use the Pythagorean theorem to find the length of ABCD. Letting x represent the length, you can solve for x: x^2 + 11^2 = 18^2, which simplifies to x^2 = 225. Thus, x = 15. The area of the rectangle is 15 * 11 = 165 square units. To find the perimeter, you can add all four sides together: 15 + 11 + 15 + 11 = 52 units.
11*11 = 121 square centimeters
The surface area of a cylinder if the radius is 3 and the height is 11 equals 263.9 square units.
nothing but 11 multiplyed by 1 equals 11. 11x1=11
circumference = 11*3.14 = 34.54 cm
