Calculate the area of a rectangle if its length is 15cm and width is 7cm.

In a rectangle, opposite sides are parallel and they are equal to each other.

The area of a rectangle is determined by multiplying the length of the shape by its width.

Let’s write the formula for determining the area of a rectangle:

S = ab;

S is the area of the rectangle;

a and b are the length and width of the rectangle.

Substitute the numerical values into the formula and calculate the area of the rectangle:

S = 15cm * 7cm = 105cm2.

Answer: the area of the rectangle is 105 cm2.
