The dimensions of the another rectangle is 2 cm and 4 cm.
According to the statement
We have to find that the perimeter of another rectangle.
So, For this purpose, we know that the
The perimeter of a shape is defined as the total length of its boundary.
From the given information:
The perimeter of a pool is 150 m. the rectangle at the right is a scale drawing of the pool. The length of each square on the grid represents 1 cm. draw another scale drawing of the pool using the scale 25 m to 2 cm.
Then
From the given rectangle,
Length of the rectangle = 5 cm
Width of the rectangle = 10 cm
Ratio of length : width = 1 : 2
Perimeter of the rectangle = 2(l + b)= 150 cm
l + b = 75 -----(1)
Since, l : b = 1 : 2
l/b = 1/2
b = 2l ------(2)
From equations (1) and (2),
l + 2l = 75
3l = 75
l = 25 m
Width 'b' = 2(25) = 50 m
Now we've to draw a rectangle with a scale = 25 : 2
Therefore, multiplier factor = 25/l = 25/2
l = 2 cm
Similarly,
50/w = 25/2
w = 4 cm
Now we are able to draw a rectangle with length = 2 cm and width = 4 cm.
So, The dimensions of the another rectangle is 2 cm and 4 cm.
