If you mean an isosceles trapezoid with parallel sides of 18 cm and 27 cm then the length of the 4th sides is 2 cm
one cm is 1/100th of a meter. if you have a length in cm then multiply it by 10^-2 to get the length in m. if you have the length in meters then multiply it by 10^2 to get the length in cm
Its length is 12 cm because 2(12+10) = 44 cm
length = 36/4.5 = 8 cm
The width is 6 cm and the length is 12 cm.

A stamp collector uses a converging lens with focal length 25 cm to view a stamp 13 cm in front of the lens.
A convex lens forms a real and inverted image of equal size only when it is kept at the center of curvature of the lens. The image is also formed at the center of curvature at the other side. Hence, the distance of object = distance of image = 50 cm. Now, focal length = � � radius of curvature = � � 50 cm = 25 cm Hope it is clear!
The image of the star will be 67.5 cm from the mirror because focal length is the raidus of curvature multiplied by 2 or (2)(C). So, therefore, 150 / 2 will give the focal length which would also be the answer.
If you mean an isosceles trapezoid with parallel sides of 18 cm and 27 cm then the length of the 4th sides is 2 cm
1/o + 1/i = 1/ff = (o x i)/(o + i)f = 11.1 cm (rounded)
The wording does not make sense.
2 cm
Use the thin lense equation. 1/f = 1/d + 1/o, where f is the focal length, d is the image distance, and o is the object distance.
