Question

from the coordinates of the Triangle formed by the line 4 x minus 5 Y - 20 = 0 and 3x + 5 Y - 15 = 0 and y axis the area of triangle is​

Answer 1

Area of Triangle  = 35/2 sq units formed by the line 4x - 5y - 20 = 0 & 3x + 5y - 15 = 0 & y -axis

Step-by-step explanation:

4x - 5y - 20 = 0

3x + 5y - 15 = 0

y axis  => x = 0

4x - 5y - 20 = 0   & x = 0

=> y = - 4

(0 , -4)

3x + 5y - 15 = 0 & x = 0

=> y = 3

(0 , 3)

4x - 5y - 20 = 0  & 3x + 5y - 15 = 0

x = 5  & y = 0

(5 , 0)

(0 , -4) , (0 , 3) & (5 , 0)

Area of Triangle  =  (1/2) | 0(3 - 0) + 0(0 -(-4)) + 5(-4 - 3) |

= 35/2 sq units

Area of Triangle  = 35/2 sq units
