If a rectangle has an area of 56 cm² and a width of 7 cm, what is its length?

• 8 cm

• 49 cm

• 63 cm

• 4 cm

Answer explanation

To find the length of the rectangle, divide the area by the width: 56 cm^2 / 7 cm = 8 cm. Therefore, the length of the rectangle is 8 cm.

• 5 cm

• 10 cm

• 20 cm

• 100 cm

Answer explanation

The area of a triangle is calculated using the formula: Area = 0.5 * base * height. Given area = 50 cm^2 and base = 10 cm, height = 2 * (Area / base) = 2 * (50 / 10) = 20 cm.
