B - 53
7 x 7 = 49 and 2 x 2 = 4, therefore 49 plus 4 is 53
The third one is the answer
(1,5)
good luck
Answer:
Ans. 64 cm
Step-by-step explanation:
we have to use the ratio of actual distance and distance on projection here.
Given,
Ratio of distance in projection and actual distance is 1:200,000
That means, 1 cm in projection will be 200,000 cm in actual distance.
Here,
Actual distance is 128 km.
we know, 1 km=100,000 cm
Now, 128 km=128,00,000 cm
So, actual distance is 128 00 000 cm.
Since, 200000 cm in actual distance means 1 cm in projection.
So,
for 12800000 cm in actual distance means 12800000/200000 cm in projection.
So, in the screen distance will be-
12800000 / 200000
=64 cm
N=199 because in order to get a a smaller negative you would have to add a positive into a negative

= 19
