Question

A moringa tree, when planted, was 90cm tall. It then grew an equal number of centimetres each month. At the end of the seventh month, it was 132cm tall. How tall was the tree at the end of the twelfth month?

Answer 1

Answer:

162 cm

132-90 = 42 cm

42/7 = 6cm

Final height = 90 + 6*12

= 90 + 72

= 162 cm
