Question

find the area of triangle whose sides are along the lines x=3 , y=0 & 4x+5y=20

Answer 1

Given that,
X = 3
Y = 0
& 
4X + 5Y = 20
First put X = 3 in the equation we will get
4 × 3 + 5Y = 20
Y = 8/5
Now, put Y = 0 in the equation we will get
4X + 5 × 0 = 20
X = 5
Area of the triangle wll be = 1/2 × 5 × 8/5
= 4 unit²

Answer 2

Answer: 4 unit square

Step-by-step explanation:

X = 3

Y = 0

4X + 5Y = 20

First put X = 3 in the equation we will get

4 × 3 + 5Y = 20

Y = 8/5

Now, put Y = 0 in the equation we will get

4X + 5 × 0 = 20

X = 5

Area of the triangle wll be = 1/2 × 5 × 8/5

= 4 unit²
