plz mark as brainliest

Step-by-step explanation:

first change m to centimeter therefore

=> 1 m=100cm

100+50= 150 cm

take x as the common factor such that when we multiply x with 2 3 and 5

and add all of them we will get 150 cm

and in the equation, we can write this as

=> 2x +3x+5x=150 cm

10x=150 cm

take x to the 150 side you will get

=> x=150/10

x= 15

therefore the longest side will be

5 x 15 = 75

Answer 2

Answer:

75 cm

Step-by-step explanation:

Let the ratios be 2x, 3x ,5x

total ratio= 10x

10x = 150 cm

x = 15 cm

2x = 2*15 = 30 cm

3x = 3*15 = 45 cm

5x = 5*15 = 75 cm

Length of the longest part is 75 cm....

hope it helps!!!
