What is the value of the height in a triangle if the area is 35 cm² and the base is 10 cm?

Using the formula $$A = \frac{1}{2} \times base \times height$$ , we find: $$height = \frac{2A}{base} = \frac{2 \times 35}{10} = 7 cm$$ .

What is the formula for the area of a rectangle?

The area of a rectangle is given by the formula: $$A = length \times width$$ .

If a rectangle has a length of 10 cm and a width of 5 cm, what is its area?

Using the formula $$A = length \times width$$ , the area is: $$A = 10 \times 5 = 50 cm^2$$ .

What is the formula for the area of a parallelogram?

The area of a parallelogram is given by the formula: $$A = base \times height$$ .

If the base of a parallelogram is 8 cm and the height is 5 cm, what is its area?

Using the formula $$A = base \times height$$ , the area is: $$A = 8 \times 5 = 40 cm^2$$ .

What is the relationship between the radius and diameter of a circle?

The diameter of a circle is twice the radius: $$diameter = 2 \times radius$$ .

If the radius of a circle is 3 cm, what is its diameter?

Using the relationship $$diameter = 2 \times radius$$ , the diameter is: $$diameter = 2 \times 3 = 6 cm$$ .

What is the formula for the area of a trapezoid?

The area of a trapezoid is given by the formula: $$A = \frac{1}{2} \times (base_1 + base_2) \times height$$ .
