Question

the perimeter of an is triangle is 42 cm.if each side has the same length then find the length of each side

Answer 1

Answer:

2x+7 = 3x+4

solve for x as follows:

start with 2x+7 = 3x+4

subtract 2x from both sides of the equation and subtract 4 from both sides of the equation to get:

 

7-4 = 3x-2x

simplify to get 3 = x

the value of x is equal to 3.

each side of the triangle will be equal to 2x+7 = 6+7 = 13.

you could have used the other formula as well because 3x+4 = 9+4 = 13.

since all the sides are equal, the third side is also equal to 13.

Answer 2

sides of a triangle=3

perimeter of the triangle=42cm

if length of each side are equal

therefore length of the each side=42÷3=14

so length of the each side s=14cm
