Find the area of a rectangle if its length is 4 cm 8 mm and its width is 2 cm 4 mm more than its length.
The first step is to calculate what the length of the rectangle is, knowing that it is 2 centimeters 4 millimeters larger than the width, which is 4 centimeters 8 millimeters. The phrase “more by” means action – addition. Let’s convert centimeters to millimeters. 1 centimeter = 10 millimeters.
2 centimeters 4 millimeters = 2 * 10 + 4 = 20 + 4 = 24 millimeters.
4 centimeters 8 millimeters = 4 * 10 + 8 = 40 + 8 = 48 millimeters.
Let’s calculate what the length is equal to.
a = 48 + 24 = 72 millimeters.
Rectangle area
A rectangle is a quadrilateral with all four corners straight. The opposite sides of the rectangle are equal. The long side of the rectangle is called the length of the rectangle, and the short side is called the width of the rectangle. The area of the rectangle is equal to the product of the length and the width. S = a * b
a – is the length.
b – is the width.
S – is the area.
Let’s calculate what is the area of the rectangle.
S = 48 * 72 = 3456 square millimeters.
Answer: 3456 square millimeters.
