Answer 1

Difference of two rectangles, one being an external rectangle and the other an internal.

Difference of two rectangles, one being an external rectangle and the other an internal.Area of external rectangle = length*breadth = 40cm*30cm = 1200cm square

Difference of two rectangles, one being an external rectangle and the other an internal.Area of external rectangle = length*breadth = 40cm*30cm = 1200cm squareArea of internal rectangle:

Difference of two rectangles, one being an external rectangle and the other an internal.Area of external rectangle = length*breadth = 40cm*30cm = 1200cm squareArea of internal rectangle:length= 40cm - 2(5cm) = 30 cm

Difference of two rectangles, one being an external rectangle and the other an internal.Area of external rectangle = length*breadth = 40cm*30cm = 1200cm squareArea of internal rectangle:length= 40cm - 2(5cm) = 30 cmbreadth = 30 cm - 2(5cm) = 20 cm

Difference of two rectangles, one being an external rectangle and the other an internal.Area of external rectangle = length*breadth = 40cm*30cm = 1200cm squareArea of internal rectangle:length= 40cm - 2(5cm) = 30 cmbreadth = 30 cm - 2(5cm) = 20 cmArea = length*breadth = 30cm*20cm = 600 cm square

Difference of two rectangles, one being an external rectangle and the other an internal.Area of external rectangle = length*breadth = 40cm*30cm = 1200cm squareArea of internal rectangle:length= 40cm - 2(5cm) = 30 cmbreadth = 30 cm - 2(5cm) = 20 cmArea = length*breadth = 30cm*20cm = 600 cm squareArea of the border = Area of external rectangle - Area of internal rectangle

Difference of two rectangles, one being an external rectangle and the other an internal.Area of external rectangle = length*breadth = 40cm*30cm = 1200cm squareArea of internal rectangle:length= 40cm - 2(5cm) = 30 cmbreadth = 30 cm - 2(5cm) = 20 cmArea = length*breadth = 30cm*20cm = 600 cm squareArea of the border = Area of external rectangle - Area of internal rectangle= 1200 cm square - 600 cm square

Difference of two rectangles, one being an external rectangle and the other an internal.Area of external rectangle = length*breadth = 40cm*30cm = 1200cm squareArea of internal rectangle:length= 40cm - 2(5cm) = 30 cmbreadth = 30 cm - 2(5cm) = 20 cmArea = length*breadth = 30cm*20cm = 600 cm squareArea of the border = Area of external rectangle - Area of internal rectangle= 1200 cm square - 600 cm square= 600 cm. square
