hope this will help you

Answer 2

Step-by-step explanation:

67) Side of the equilateral triangle =3.5

Perimeter of the equilateral triangle=3.5+3.5+3.5

=10.5

68) Length of the rectangle=7.1

Breadth of the rectangle=2.5

Area of the rectangle = l×b

=7.1×2.5

17.75

69) Distance covered by the 2 wheeler in 1 liters of petrol=55.3km

Distance covered by the 2 wheeler in 10 liters of petrol =55.3×10

=553km
