Answer:
Actual height of the building is 670 m
Step-by-step explanation:
We have been the actual height of a Ferris wheel which is 134 m. Along with it we are also given the scaled down heights of a Ferris wheel and a building. Using this data we have to find the actual height of a building.
Actual height of Ferris wheel = 134 m.
Height of Ferris wheel using the scale = 0.65 cm
Height of building after using the scale - 3.25 cm
Let, the actual height of building be x meters.
Since, the same scale is being used, the ratio of actual heights to that of scaled down heights must be the same for both objects.
i.e.
Ratio of Actual Height to scale height of Ferris Wheel = Ratio of Actual Height to scale height of the building
Using the values, we get:
The units of actual heights are in meters, so this means the actual height of the building is 670 m
Answer:
Area of rectangle is
Perimeter of Rectangle is .
Step-by-step explanation:
Given:
Let the width of the rectangle be 'w'.
Also Given:
A rectangle has a length that is 5 meters greater than the width.
Length of rectangle =
We need to write expression for Area of rectangle and Perimeter of rectangle.
Solution:
Now we know that;
Perimeter of rectangle is equal to twice the sum of the length and width.
framing in equation form we get;
Perimeter of rectangle =
Also We know that;
Area of rectangle is length times width.
framing in equation form we get;
Area of rectangle=
Hence Area of rectangle is and Perimeter of Rectangle is
