Question

Calculate the perimeter...

Answer 1

Answer

14.8 units

Explanations

First find the lengths of the triangle.

YX = √(2²+5²) = √(4+25) =√29

YZ = √(2²+3²) = √(4+9) = √13

XZ = √(5²+3²) =√(25+9) = √34

Perimeter = √29 + √13 + √34

= 14.82 units

Answer 2

The two bigger sides measure 6 units according to the image and the smallest on 3 units.

The perimeter of a triangle is the sum of the sides:

6 + 6 + 3 = 15

The answer is the third option, closest one to 15 units.
