Answer:
The tree is <u>6.36 meters</u> tall.
Step-by-step explanation:
Given:
Tonya is 1.3 meters tall.
She stands 7 meters in front of a tree and casts a shadow 1.8 meters long.
Now, to find the height of the tree.
Let the height of tree be .
As, Tonya is 1.3 metres tall and casts 1.8 metres shadow.
Thus, height of 1.3 meters is equivalent to 1.8 metres.
So, is equivalent to 7+1.8 meters.
As, she stands 7 meters in front of a tree and casts a shadow 1.8 meters long.
Now, we solve by using cross multiplication method:
<em>By cross multiplying we get:</em>
<em>Dividing both sides by 1.8 we get:</em>
Therefore, the tree is 6.36 meters tall.
