Question

The first side of a triangle is cm long. The second side is twice as long as the first. The third side is 5 cm longer than the second side. The perimeter of the triangle is 1 metre.
write an equation to show this.
solve the equation.
what is the length of the longest side of the triangle.

Answer 1

Step-by-step explanation:

x+2x+2x+5 = 1m

x+2x+2x+5 = 1000cm

4x+5 = 1000 cm

4x = 1000-5

x= 996/4

= 248.75cm

2x= 2×248.75

= 497.5 cm

2x+5 = 2×248.75+5

= 497.5+5

502.5 cm

the length of a longest side is 502.5 cm

I'm not sure about it
