The relationship between her height and the tree's is an illustration of ratios and proportions

The height of the tree is approximately 2.11 meters

Her height is represented as:

\mathbf{h =1.85}

At 12 noon, the length of the tree's shadow and her distance from the shadow are given as:

\mathbf{D =39.75}

\mathbf{d =34.9}

To calculate the height (H) of the tree, we make use of the following equivalent ratios

\mathbf{H : h =D : d}

So, we have:

\mathbf{H : 1.85 =39.75 : 34.9}

Express ratio as fraction

\mathbf{\frac{H }{ 1.85 }=\frac{39.75 }{ 34.9}}

Multiply both sides by 1.85

\mathbf{H=1.85 \times \frac{39.75 }{ 34.9}}

\mathbf{H=2.11}

Hence, the height of the tree is approximately 2.11 meters

Inessa05 [86]
I totally forgot that I am having meeting at my work place. All of sudden, I remembered that meeting through a hint given by my colleague while having discussion about our project work. I have to present a topic which I didn't prepare yet. Meeting is at 1.15pm. OMG! It's already 12.30 pm. Within few minutes I went to the meeting place with my topic. When I entered the meeting hall, the time was 12.53pm. I was happy to know that I arrived 22 minutes earlier.
