Answer:
The Perimeter is (2x +23 ) inches.
Explanation:
Given:
Figure is of a Triangle Shape.
Perimeter of a Triangle is Sum of all the three sides of a triangle.
If a triangle having Sides a, b , and c , then the perimeter of the triangle is given by
Perimeter = a + b + c
Here the sides are (2x - 3 ) , (21 - x ) and ( x +5 ) .
∴ Perimeter = (2x - 3 ) + (21 - x ) + ( x +5 )
∴ Perimeter = 2x + 21+ 5 - 3 +x -x
x -x will cancel each other as x -x =0.
∴ Perimeter = (2x + 23) inches
∴
