Andy Ng Jun Wei's answer to Ho jun jie's Secondary 4 E Maths question.
Hello, i think theres some miscalculation of the height. It should be 8cm. :)
Yup it is 8, just change accordingly for the second part, you will get a right final answer, tell me if you still can't get it
My method for second part is still the right way to solve this question, so just change accordingly
