Find the area of triangle whose sides are along the lines x=2 and y=0 and 4x+5y=20.​

Answer 1

Answer:

since the equation is given then

Step-by-step explanation:

4x+5y=20 put the values

let X be base and y be height

putting the values

4*2+5*y=20

8+5y=20

20-8=5y

12=5y

2.4 =y

since X is given and we have find the y

put in formula

1/2*2*2.4==2.4 so area is 2.4cm2

Answer 2

Answer:

See this attachment

After plotting the lines on graph it will look like above attachment.

From picture it is clear that,

Base of triangle=(5-3)=2units

Height of triangle=2.4units

Therefore, Area of triangle=1/2×b×h

=1/2×2×2.4= 2.4 sq unit
