Question

14. Find area of A formed by lines x = y, x + y = and y axis.​

Answer 1

Answer:

Correct option is

A

716 sq. unit

To find B

3x−2y=−1 and x+y=3

solving above two equations we get

y=2 and x=1

B=(1,2)

To find C

3x−2y=−1 and x−3y=−9

solving above two equations we get

y=27/6 and x=15/7

C=(715,627)
