1. Nëse lartësia h dhe brinja a e paralelogramit dyfishohen, atëher siperfaqja e tij:

Dyfishohet

Trefishohet

Katerfishohet

Tetëfishohet

If the height and base of a parallelogram are doubled, then its area is quadrupled. Therefore, if the height and base are multiplied by four, the area will be multiplied by four as well. This means that the area of the parallelogram is quadrupled, or "katerfishohet" in Albanian.

3. Cili paralelogram e ka syprinen me të madhe:

A=20, h=20

A=21, h=19

A=40, h=9.9

A=9.9, h=40

The given answer is correct because the area of a parallelogram is calculated by multiplying the length of the base (a) by the height (h). In this case, the base (a) is 20 and the height (h) is also 20. Therefore, the area of the parallelogram is 20 * 20 = 400.

Explanation

The given answer is correct because the area of a parallelogram is calculated by multiplying the length of the base (a) by the height (h). In this case, the base (a) is 20 and the height (h) is also 20. Therefore, the area of the parallelogram is 20 * 20 = 400.

The formula for the perimeter of a rectangle is P = 2(a + b), where a and b are the lengths of the sides. In this case, we are given that one side, a, is 8 cm. The formula for the area of a rectangle is A = a * b, where a and b are the lengths of the sides. We are given that the area, A, is 16 cm². By rearranging the area formula, we can solve for the length of the other side, b, which is 2 cm. Plugging the values of a and b into the perimeter formula, we get P = 2(8 + 2) = 20 cm. Therefore, the correct answer is 20.

The formula for the area of a triangle is A = (1/2)bh, where A is the area, b is the base, and h is the height. In this case, the height is given as 8cm and the area is given as 24cm^2. Plugging these values into the formula, we can solve for the base: 24 = (1/2)(b)(8). Simplifying the equation, we get 24 = 4b. Dividing both sides by 4, we find that b = 6cm. Therefore, the length of the base is 6cm.

If the length of one side of a right triangle (a) is 12 and the length of the hypotenuse (c) is 13, then the length of the other side (b) can be found using the Pythagorean theorem: a^2 + b^2 = c^2. Plugging in the given values, we have 12^2 + b^2 = 13^2. Simplifying this equation, we get 144 + b^2 = 169. Subtracting 144 from both sides, we have b^2 = 25. Taking the square root of both sides, we find that b = 5. Therefore, the length of the other side of the triangle is 5, which is the correct answer.

The given numbers are arranged in a sequential pattern where each number is decreasing by a certain value. The difference between the first and second numbers is 157, the difference between the second and third numbers is 235.5, and the difference between the third and fourth numbers is 549.5. Therefore, the next number in the sequence should be 549.5 less than the previous number, which is 314. Therefore, the correct answer is 549.5.

The surface area of a deltoid can be calculated using the formula (large side x small side) / 2. In this case, the large side is 39, the small side is 25, so the surface area is (39 x 25) / 2 = 975 / 2 = 487.5. However, since the surface area of a deltoid is always a whole number, we need to find the closest whole number to 487.5, which is 488. Therefore, the correct answer is 488, which is not listed as an option. Therefore, the correct answer is not available.
