15 cm is the measure of the longest side

Step-by-step explanation:

The perimeter is 35cm. What is the measure of the longest side?

Given the ratio 2:2:3 and we know that a + b + c = the Perimeter, thus:

[tex]a+b+c = 35[/tex]

[tex]2x+2x+3x=35cm[/tex]

[tex]7x=35cm[/tex]

[tex]x = 5cm[/tex]

Finding the values of each side

[tex]a = 2(5) = 10cm[/tex]

[tex]b = 2(5) = 10cm[/tex]

[tex]c = 3(5) = 15 cm[/tex]

∴ 15 cm is the measure of the longest side
