Answer:

  • 117 cm; 91 cm; 208 cm

Step-by-step explanation:

According to the given ratio the height of the plants is 7x and 9x.

<u>The difference of heights is 26 cm:</u>

  • 9x - 7x = 26
  • 2x = 26
  • x = 13

a) <u>The taller plant is:</u>

  • 13*9 = 117 cm

b) <u>Shorter plant is:</u>

  • 7*13 = 91 cm

c) <u>Their total height is:</u>
