Rowen uses a scale factor of 1.5 to make a scale drawing of a square. How did the area of the scans drawing compare to that of the original square. Write you answer in decimal form.
The scale factor of 1.5 means that each side of the scaled drawing is 1.5 times longer than the original square.
When the scale factor is applied to the sides, the area of the scaled drawing would be 1.5^2 = 2.25 times larger than the original square.
Therefore, the area of the scaled drawing is 2.25 times the area of the original square. In decimal form, this is 2.25.
George makes a 1/25 scale drawing of a triangular sail. The triangle in his drawing is 2 feet high with a base of 1 foot. What is the area of the sail
Since the scale factor is 1/25, the dimensions of the scaled drawing are 1/25 times the actual dimensions of the sail.
Height of the scaled triangle = 2 feet * 1/25 = 2/25 feet
Base of the scaled triangle = 1 foot * 1/25 = 1/25 feet
The area of a triangle is given by the formula: Area = 1/2 * base * height
Plugging in the values:
Area = 1/2 * (1/25) * (2/25) = 1/2 * 2/625 = 1/625 square feet
So, the area of the scaled drawing of the triangle sail is 1/625 square feet.
