Question

The three sides of a triangle are x,2x and x+3. If the Perimeter is 23m , the largest side is
A) 5
B) 10
C) 8
D) 12

Answer 1

Hey friend....
Here is your answer...

X + 2x + x + 3=23
4x=20
x=5m

Largest side is 2x = 2*5=10

Answer 2

perimeter= sum of all sides
x+2x+x+3=23
4x+3=23
4x=20
x=5
therefore, x=5, 2x=10 and x+3=8.
therefore 10 will be the largest side
