= $$\\ \frac { 17 }{ 2 }$$ m
Area = (Side)² = Side x Side
= $$\\ \frac { 17 }{ 2 }$$ x $$\\ \frac { 17 }{ 2 }$$ m²
= $$\\ \frac { 289 }{ 4 }$$ m²
= $$72\frac { 1 }{ 4 }$$ m²

= Rs $$\\ \frac { 255 }{ 4 }$$
Cost of 34 litres of petrol
= $$\\ \frac { 255 }{ 4 }$$ x 34
= $$\\ \frac { 255X17 }{ 2 }$$
= $$\\ \frac { 4335 }{ 2 }$$
= Rs $$2167\frac { 1 }{ 2 }$$

Solution:
Distance covered in 1 hour = 1020 km.
Distance covered in $$4\frac { 1 }{ 6 }$$ hours
= 1020 x $$4\frac { 1 }{ 6 }$$
= 1020 x $$\\ \frac { 25 }{ 6 }$$ km
= $$\\ \frac { 25500 }{ 6 }$$
= 4250 km. Ans.

Total length of piece of chord
= $$71\frac { 1 }{ 2 }$$
No. of pieces = 26

Question 13.
Solution:
Area of a room = $$65\frac { 1 }{ 4 }$$ m²
Breadth = $$5\frac { 7 }{ 16 }$$ m
