Answer:
8. 1m = 44 whole 4/5
= ₹ 224/5
3 whole 3/4 = 3 whole 3/4 × 224/5
or, 15/4m = 15/4×224/5
= 3×56
= ₹168
10. length of each piece= 6 whole 3/4
= 27/4m
original length = 27/4×8
= 27×2
= 54m
11. length = 16 whole 1/2 = 33/2
breadth = 12 whole 3/4 = 51/4
perimeter = 2(l+b)
= 2(33/2+51/4)
= 2(66/4+51/4)
= 2 × 117/4
= 117/2
= 58 whole 1/2 m
12. length = 36 whole 3/5 = 183/5
breadth = 16 whole 2/3 = 50/3
area = 183/5 × 50/3
= 61×10
= 610 m²
