Question

there is a rectangle field of length 122m and breadth 92m a wall 1m thick is bonudary​

Answer 1

answer :- Area of a rectangle is discussed here. We know, that a rectangle has length and breadth.

Let us look at the rectangle given below.

Area of Regular Figures

Each rectangle is made of squares. The side of each square is 1 cm long. The area of each square is 1 square centimeter.

step by step explanation :- The rectangle ABCD has 8 such squares. Therefore, its area is 8 sq cm. Similarly we can find the areas of the other rectangles by counting the number of squares. We also note the length and breadth of each rectangle and write in the table below:

Rectangle

ABCD

LMNO

PQRS

Area

8 sq. cm

12 sq. cm

6 sq. cm

Length

4 cm

4 cm

2 cm

Breadth

2 cm

3 cm

3 cm

Length × Breadth

4 cm × 2 cm = 8 cm2

4 cm × 3 cm = 12 cm2

2 cm × 3 cm = 6 cm2

In each case we observe the length × breadth = Area of the rectangle.

Therefore, area of rectangle = length × breadth = l × b sq. units
