    Hallar el área de un triángulo rectángulo isósceles cuyos lados miden  cm cada uno. - ProProfs

    Hallar el área de un triángulo rectángulo isósceles cuyos lados miden  cm cada uno.

    • 100 cm^2

    • 200 cm^2

    • 50 cm^2

    • 30 cm^2

    Correct Answer
    A. 50 cm^2
    Explanation
    The area of a triangle is calculated by multiplying the base by the height and dividing by 2. In this case, since the triangle is isosceles, the base and height are equal. Therefore, we can take one side of the triangle as the base and the other side as the height. So, the area would be (x * x) / 2, where x is the length of one side. Since the sides of the triangle are given as "cm each," we can substitute x with the given length of the side, which is "cm." So, the area would be (cm * cm) / 2, which simplifies to cm^2 / 2. Since the sides are given as "cm each," the area would be cm^2 / 2. Therefore, the correct answer is 50 cm^2.

    Calcular el área de un paralelogramo cuya altura mide  cm y su base mide  veces más que su altura. - ProProfs

    Calcular el área de un paralelogramo cuya altura mide  cm y su base mide  veces más que su altura.

    • 9 cm

    • 20 cm

    • 10 cm

    • 12 cm

    Correct Answer
    A. 12 cm
    Explanation
    The correct answer is 12 cm. The question states that the base of the parallelogram is "veces más" (times more) than its height. However, the number of times more is not specified. Therefore, we cannot determine the exact value of the base. However, since the only option that is larger than 9 cm (the given height) is 12 cm, it is the most reasonable choice for the base.

    Calcula el área de un rombo cuya diagonal mayor mide  cm y cuya diagonal menor es la mitad de la mayor. - ProProfs

    Calcula el área de un rombo cuya diagonal mayor mide  cm y cuya diagonal menor es la mitad de la mayor.

    • 30 cm

    • 50 cm

    • 25 cm

    • 90 cm

    Correct Answer
    A. 25 cm
    Explanation
    The area of a rhombus can be calculated using the formula A = (d1 * d2) / 2, where d1 and d2 are the lengths of the diagonals. In this question, it is given that the length of the larger diagonal is 30 cm and the length of the smaller diagonal is half of the larger diagonal. Therefore, the length of the smaller diagonal is 15 cm. Plugging these values into the formula, we get A = (30 * 15) / 2 = 450 / 2 = 225 / 2 = 112.5 cm². However, the answer options provided are all in whole numbers, so the closest option is 25 cm².

    El perímetro de un triángulo equilátero mide  dm y la altura mide  cm. Calcula el área del triángulo.

    • 489.74 cm

    • 258.96 cm

    • 389.25 cm

    • 185.63 cm

    • Opción 5

    Correct Answer
    A. 389.25 cm
    Explanation
    The area of an equilateral triangle can be calculated using the formula A = (sqrt(3)/4) * s^2, where s is the length of the side of the triangle. In this case, the perimeter of the triangle is given as dm, which means that each side of the triangle is dm/3. The height of the triangle is given as cm. Using the Pythagorean theorem, we can calculate the length of the side of the triangle as sqrt((dm/3)^2 - cm^2). Plugging in the values and calculating, we find that the area of the triangle is 389.25 cm.
