**Exercise 66:**

**Solution 1:**

- Area of a rectangle = length ×
__breadth__ - Area of a square = side ×
__side__= (__side__)^{2}

**Solution 2:**

Length of the rectangle = 4 cm

Breadth of the rectangle = 2 cm

Area of a rectangle = length × breadth

= 4 × 2

= 8 sq. cm

Thus, the area of the rectangle is 8 sq. cm.

**Solution 3:**

Side of the square = 40 cm

Area of a square = (side)^{2} = (40)^{2} = 1600 sq. cm

Thus, the area of the square is 1600 sq. cm

**Solution 4:**

Length of the pit, l = 2 m

Breadth of the pit, l = 2 m

Area of the pit =l × b = 2 × 2 = 4 sq. m

Length of the plot, l = 12.4 m,

Breadth of the plot, b = 10.2 m

Area of the plot = l × b = 12.4 × 10.2 = 126.48 sq. m

Now, area of the plot after the pit is dug = 126.48 − 4= 122.48 sq. m

Thus, the area of the plot after the pit is dug is 122.48 sq. m.
