Answer:
251.5 cm
Step-by-step explanation:
1 m = 100 cm
1 cm = 10 mm
2 m + 50 cm + 15 mm =
= 2 m * (100 cm)/m + 50 cm + 15 mm * (1 cm)/(10 mm)
= 200 cm + 50 cm + 1.5 cm
= 251.5 cm
The area of the shaded rectangle is 18 square units.
<h3>
How to get the area of the shaded region?</h3>
The shaded region is the framed rectangle, and the white part is the frame.
We know that the frame is 2 units wide, and the measure of the rectangle and the frame are:
- width = 7 units
- length = 10 units
Now, if we remove the frame, we will remove 2*2 units = 4 units for each measure (because for each measure we have the frame in both sides).
So the measures for the shaded rectangle are:
- width = 7 units - 4 units = 3 units
- length = 10 units - 4 units = 6 units.
And the area of a rectangle is given by the product between the width and length, then we have:
A = (3 units)*(6 units) = 18 square units.

Question 1
Let the scale factor be k.
Then, we have the mapping
This implies that:
We equate any corresponding component find the value of the scale factor k.
6k=2
Hence the scale factor is
