# Calculate the area of a rectangle that is 85 mm long and 23 mm wider.

March 31, 2021 | education

| To solve the problem, you need to know the formula for finding the area of a rectangle:

S = a * b,

where a is the length of the rectangle,

b is the width of the rectangle.

It is known from the problem that the length of the rectangle is 85 mm, and the width is 23 mm less. Subtract 23 mm from the length of the rectangle, thereby finding the width:

85 – 23 = 62 (mm) – the width of the rectangle.

Let’s calculate the area of the rectangle:

S = 85 * 62 = 5270 (mm ^ 2).

Answer: The area of the rectangle is 5270 mm ^ 2.
