Area of Rectangle
Area of Rectangle
The area of a rectangle is calculated in units by multiplying the width (or breadth) by the Length (or Height) of a rectangle.
The formula for the Area of a Rectangle = length x breadth
The area of any rectangle is calculated once its length and width are known.
Illustration: Find the area of the rectangle whose length is 15 cm and the width is 4 cm?
Solution: Given, Length = 15 cm and Width = 4 cm
Area of a rectangle = Length × Width = 15 × 4 = 60 sq cm
So the area of rectangle =
Illustration: Given that the area of recatngle is 75 sq cm. if one side is 5 cm find the other side.
Solution: One side of the rectangle = 5cm , Let the other side of the rectangle = y cm
Area of rectangle = Length X breadth = 5 X y sq cm
According to the question: Area of rectangle = 75 sq cm
OR 5 X y = 75 sq cm
Hence the other side = 15 cm
Illustration: Find the area of rectangle whose dimensions are given below.
Length = 12.5 cm , Breadth = 50 cm
Solution: Area of the rectangle = Length × Width
= 12.5 X 50
Hence, Area of the rectangle is .
