The area of the first rectangle is 24cm2, and its width is 3cm, the area of the second rectangle is 18cm2

The area of the first rectangle is 24cm2, and its width is 3cm, the area of the second rectangle is 18cm2, and its width is 2cm. which rectangle is longer and by how much?

The length of the rectangle can be expressed from the formula for determining its area.

If S = a * b, hence a S: b. Since the first factor is equal to the quotient of the product and the second.

Let’s find the length of the first figure, provided that S = 24 cm² and width = 3 cm:
a = 24: 3 = 8 cm.

S = 18, b = 2 cm.
a = 18: 2 = 9 cm.

It turns out that the length of the second rectangle is larger by:
9 – 8 = 1 cm.
