I am 1 meter tall and the top of the tree I am standing under reaches 7 meter higher than me. How high is the tree? A) 5 m B) 6 m C) 7 m D) 8 m
Hint: We will first try and depict what the question wants to convey and draw a basic rough diagram to see the same and then we will see that summing up both the numbers will lead us to the height of the tree.
Complete step-by-step answer: We are given that the person is 1 m tall and he / she is standing under a tree which goes 7 m above their head. Let us try to depict the same with a diagram.
We see that the person is 1 meter tall and the height of the tree above him is 7 meters. We obviously know that both the person and tree will be standing on the ground only. So, if we clearly observe the height of the tree, the total would be the sum of the height of the tree above the person and the height of the person himself / herself. So, height of tree will be given by: Height of tree above person + Height of person Hence, the height of the tree = 7 m + 1 m = 8 m. Hence, the answer is 8 meters.
Hence, the correct option is (D).
Note: The students must make a rough diagram to see the things clearly. If they want to they can even draw lines for both the person and tree as well instead of a clearer diagram. They just need the diagram to understand the given conditions. Some facts about addition:- Addition of 0 to any number does not change anything. Addition of any number to itself will always result in zero. In simpler words for all real numbers a, a + (-a) = 0 always. The number or values being added are called addends and the answer we get after adding them is called the sum.
