<u>Answer:</u>
The height of the tower nearby the pole is 102 m.
<u>Solution:</u>
Given,
Height of the pole = 3.5 m
Length of the shadow of the pole = 1.47 m
Length of the shadow of the tower nearby = 42.75 m
Let us assume the height of the tower as x
On solving for x we get,
On rounding off to the nearest meter we get,
x=102 m
The height of the tower is 102 meter.
For question 4, units,
For question 5, units.
Step-by-step explanation:
Step 1:
Since the given polygons are similar to each other, all the ratios of one polygon to the other will remain equal for all the values of the two similar polygons.
We take the ratio of the same sides of both polygons i.e. the ratio of the lengths or the ratio of the widths.
Step 2:
For question 4, the first rectangle has a length of 9 units while the width is 3 units.
For the second rectangle, the length is x as x is greater than the width in the first rectangle. The width is 6 units.
The ratio of the first rectangle to the second is;
So
units.
Step 3:
The shapes in question 5 are made of a square and a triangle.
For the first shape, the side length is 6 units while the side of the triangle is 10 units.
For the second shape, the side length is 5 units while the side of the triangle is x units.
The ratio of the first shape to the second is;
So
units.
