Question

the area of the triangle formed by lines x=3, y=4 and x=y is....

Answer 1

Answer:

$0.5 unit^2$

Step-by-step explanation:

Refer the attached figure

$x=3$ blue line

$y=4$  -- Green line

$x=y$ blue line

So, Triangle ABC is formed

AB = Base = 1 unit

AC= Perpendicular = 1 unit

So, Area of triangle = $\frac{1}{2} \times base \times height$

Area of triangle = $\frac{1}{2} \times 1 \times 1$

Area of triangle = $0.5 unit^2$

Hence the area of the triangle is $0.5 unit^2$

Answer 2

Step-by-step explanation:

Refer the attached figure

x=3x=3 blue line

y=4y=4 -- Green line

x=yx=y blue line

So, Triangle ABC is formed

AB = Base = 1 unit

AC= Perpendicular = 1 unit

So, Area of triangle = \frac{1}{2} \times base \times height
