8 cm is difference in perimeter before and after the piece is cut off
Step-by-step explanation:
initial perimeter = 10 + 15 + 6 + 7 + 4 + 22
=64 cm
A rectangular piece of 10 cm x 15 cm is cut off
Size of two pieces
10 * 15 cm & 4 * 7 cm
Perimeter of 10 * 15 cm = 2(10 + 15) = 50 cm
Perimeter of 4 * 7 cm = 2(4 + 7) = 22 cm
Total Perimeter after cutting = 50 + 22 = 72 cm
difference in perimeter before and after the piece is cut off = 72 - 64 = 8 cm
