Question

find the perimeter of triangle of vertices( 0 ,4)(0;0 )and(3;0) fr chapter 7 class 10 coordinate geometory​

Answer 1

Answer:

To find the perimeter of a polygon, you need to add the length of all sides of the polygon.

Therefore,

Perimeter of Polygon=Sum of all

sides of

polygon

If you plot the points on a graph, you will get x=3 and y=4

Now, we need to find out the third side of the triangle, i.e., the Hypotenuse.

Therefore,

(Hypotenuse)^2=(one side)^2 + (other

side)^2

Hypotenuse = √(one side)^2+(other

side) ^2

= √(3)^2 + (4)^2

= √ 9 + 16

= √25

Hypotenuse = 5

Therefore,

Perimeter of Triangle = 3+4+5

= 12
