25x18= 450

450x3=1350

1350/150 =9

so he needs 9ribbons

Answer:

Perimeter of the rectangular painting=2(L+B)

2×(25+18)cm =2×43cm = 86cm

Total perimeter of the rectangular painting if it was fixed with ribbon 3 times =3×86 cm = 258 cm

Length of ribbon Anju had= 150 cm

Therefore, the length of ribbon required to fix the painting 3times = 258 cm - 150 cm = 108 cm.
