Question

Suresh has a rectangular sketch, which he needs to draw on a paper of length and breadth 32 units and 16 units respectively, using a plotter. Plotter is a device which is attached to a computer like a printer. It is used for drawing complicated sketches. Plotter accepts only positive coordinates where the point (0,0) is the left-bottom corner of the paper . The sketch ABCD needs to be centrally aligned on the paper. Find the coordinates of A,B,C and D to be plotted to get the sketch plotted as needed.
(a) The coordinates of point O in the sketch 2 is _________.
(i) ( 0, 0 ) (ii) ( 16, 8 ) ( iii) ( 8, 16 ) (iv) ( 16, 32 ) 1
(b) The coordinates of A, B, C, D are :
(i) (32, 10), (32, −10), (32, 6), (32, −6) (ii) (19, 10), (19, −10), (13, 6), (13, −6) (iii) (13, 10), (19, 10), (19, 6), (13, 6) (iv) (13, −10), (19, 10), (13, −6), (19, −6) 1
(c) In the sketch 2, if the point O divides AC in the ratio k : 1 , then the value of k is _____________.
(i) 2 (ii) 1 (iii) 1 2 (iv) 3 1
(d) The point on the y-axis (in sketch 2) which is equidistant from the points B and C is _______.
(i) ( 0, 8 ) (ii) ( 8, 0 ) (iii) ( −8, 0 ) (iv) ( 0, −8 )
