A square sheet of side 2 cm is cut from each corner of a rectangular piece of an aluminium sheet of length 12 cm and breadth 8 cm. Find the area of the leftover aluminium sheet.

Options

A. `60cm^(2)`
B. `80cm^(2)`
C. `100cm^(2)`
D. `120cm^(2)`

Answer

B

Explanation

Area of each square cut out from the rectangular
sheet `=2xx2=4cm^(2)`
Area of the rectangular sheet `=12xx8=96cm^(2)`
The required area = Area of the rectangular sheet - Total area of the square cut out
The required area = `96 - 16 = 80 cm^(2)`
