The perimeter of any triangle is the sum of the lengths of the three sides. Are you asking about a specific triangle? "On a grid" doesn't describe a triangle very well.

### All three sides of a triangle are equal in length of one side is 2x+5 and one side is 4x-3 find the perimeter of the triangle

If all sides are equal then 2x + 5 = 4x - 3
2x = 8
x = 4

so the perimeter is 3 times either expression above
3 * (8 + 5) = 39

### Square 1 has a side length of x, and square 2 has a side length of y. Square 2 is formed by joining the midpoints of the sides of square 1 in order. If x = 2, find the ratio of the perimeter of square 1 to...

Using the Pythagorean Theorem in one of the corner triangles you get
y^2=2*(x/2)^2
Thus, y=(SQRT( 2))*(x/2)
The ratio of the perimeters is equal to the ratio of the sides
P2/P1=y/x=SQRT(2)/2=1/SQRT(2)

### (9,7),(8,-3),and(2,-6) find the perimeter

From the three points you give, the perimeter appears to be the three sides of a triangle going from (9, 7) to (8, -3) to (2, -6) and back to (9, 7).

Or are you actually asking for something else? The length, perhaps? That would be about 31.5 .

### The height of equilateral triangle is 7root3cm find its perimeter

Let ABC be the equilateral triangle,
and PC be the line joining the mid point of A and C.
We know that equilateral triangle has equal angles which means

Now,
in triangle AHC
Sin(THETA) = AH/AC

That is...
Sin(60) = (7root3)/AC

or AC = (7root3)/Sin(60)

AC=14

Perimeter of equilateral triangle ABC = 3 x Side
= 3 x 14
= 42
