MARK AS BRAINLEST!!
It's a simple ratio table.
3 years 7 years 10 years
180 cm 368 cm
The difference between 3 and 7 is 4.
The difference between 180 and 368 is 188.
So every 4 years it increases 188 cm. A rate change of 4/188 simplify this fraction to be 1/47 so every 1 year it increases by 47 cm.
So 7 to 10 years is 3 years, so 47 x 3 = 141cm.
