{Two Hours Allowed.) 
1. The area of a right-angled triangle is 10,000 sq. feet, its base 
is 250 ft. long ; draw it to a scale of 50 ft. to the inch, and note the 
length of the hypotenuse, and the angles of the triangle. 
2. The sides of a quadrilateral taken in order are A B = 1250 ft., 
B C = 1430 ft., C D = 1800 ft., and D A = 1140 ft., the diagonal 
B D = 1320 ft. ; draw the figure to a scale of 400 ft. to an inch, and 
find its area ; also note the angle B C D as measured by a protractor. 
3. A square field has an area of 20 acres ; find the length of one 
of its sides. 
4. A cylindrical reservoir is 20 ft. high ; the diameter of its base 
is 20 ft. ; how many cubic feet of water can^it contain, and, if made 
of iron plates, how many square feet of plate are there in the upright 
part, neglecting overlap. 
5. Draw a scale of 60 ft. to the inch, of such a length and so 
divided that any distance from 5 ft. to 300 ft. can be measured on it. 
Draw a line to represent on the scale 135 ft. 
6. A, B, C, D, are four points taken in order along a straight road ; 
P, Q, E, points between A and B, B and C, C and D respectively ; 
when a level is at P the readings of the stafi" are 8 ft. at A, 8"5 ft. at 
B ; when at Q, the readings are 6-7 at B, 5*2 at C ; when at E the 
readings are 4-1 at C, 6-3 at D ; if A is 100 ft. above the datum line, 
what are the heights of B, C, and D ? If the level had been kept at 
P, what would have been the readings of the staff at C and at D ?
