1. The area of a field is 50,000 sq.m. The length and breadth of the field, on the map
are 10 cm and 8 cm respectively. Construct a diagonal scale, which can read up to
one metre. Mark the length of 236 meters on the scale. Find the R.F of the scale?

2. The foci of an ellipse are 100 mm apart and the minor axis is 70 mm long. Determine
the length of the minor axis and draw half the ellipse by concentric circles method
and the other half by Oblong method. Draw a curve parallel to the ellipse and 25
mm away from it.

3. Draw the projections of a circle of 50 mm diameter resting in the H.P. on a point A
on the circumference, its plane inclined at 45 degrees to the H.P. and the diameter
AB making 30 degrees angle with the V.P.
[16M]
4. A hexagonal prism, has a face on the H.P. and the axis parallel to the V.P. It is cut
by a vertical section plane, the H.T. of which makes an angle of 45 degrees with xy
and cuts the axis at a point 20 mm from one of its ends. Draw its sectional front
view and true shape of the section. Side of the base 25 mm long ; height 65mm
long.
[16M]
5. A hexagonal prism of side of base 30 mm and height 60 mm is resting on HP with
one of its base edges parallel to VP. Right half of the solid is cut by an upward plane
inclined at 60o to the ground and starting from the axis and 3
