Answer 1

Given,

The coordinates of the three points are = (9,1) , (-3,-2) and (5,-2)

To find,

The perimeter of the given triangle.

Solution,

We can simply solve this mathematical problem by using the following mathematical process.

Point A = (9,1)

Point B = (-3,-2)

Point C = (5,-2)

Length of AB = √(9+3)²+(1+2)² = √(12)²+(3)² = √(144+9) = √153 units = 12.37 units

Length of BC = √(5+3)²+(-2+2)² = √64+0 = 8 units

Length of CA = √(9-5)²+(1+2)² = √16+9 = √25 = 5 units

Perimeter = (12.37+8+5) = 25.37 units (approx)

Hence, the approximate perimeter of the given triangle is 25.37 units.
