Scale factor shows by how much the original model has been multiplied or divided by to get the measurements of the drawing .
In this case the ladybug is 8 mm long but drawing length is 2 cm.
Let’s convert both into the same units
2 cm -20 mm
Original - 8 mm
Painting -20mm
X - scale factor
20 = X * 8
X = 20/8 = 2.5
The ladybug has been multiplied/ enlarged by a scale factor of 2.5 to draw the painting
yes, since you need it know then take the asnwer and i'll explain later (:

Answer:
460 mi²
Step-by-step explanation:
The surface area consists of 3 rectangles of the sides, and the two base triangles.
The front rectangle has dimensions of 10x11, so it's area is 110 in²
The left side rectangle has dimensions of 10x11, so it's area is 110 in²
The right side rectangle has dimensions of 12x11, so it's area is 132 in²
The top and bottom triangles have a base of 12 and a height of 8, so their area is
A = (1/2)(12)(8) = 108/2, but there are 2 of them, so their combined area is (108/2)(2) = 108 in²
The total surface area is 110 + 110 + 132 + 108 = 460 mi²
