Tracy used the expression (25.6) (16.2) + (25.6) (36.5) + (16.2) (37.8) to find the surface area, in square centimeters, of the

rectangular pyramid below.
A rectangular pyramid. The rectangular base has a length of 25.6 centimeters and width of 16.2 centimeters. 2 triangular sides have a base of 25.6 centimeters and height of 36.5 centimeters. 2 triangular sides have a base of 16.2 centimeters and height of 37.8 centimeters.

Which statement best describes her work?
Tracy’s answer will be incorrect because she forgot the factor One-half in the expression representing the area of the triangular faces.
Tracy’s answer will be incorrect because the pyramid has five faces and her expression finds the sum of only three products.
Tracy’s answer will be correct because she made use of the fact that 2 (one-half) = 1 in her expression.

So 25.6 + 16.2 + 25.6 + 36.5 + 16.2 + 37.8 = 1961.48

I would say the second statement would best describe her work, because it is giving the most detail out of those statements.

Hope this helps!

I need to know the answer

It would be 3/16.
In the previous post you had 54 which you didn't put into a fraction.

6x-3/2-3x=5/4-x-2
Which simplifies to:
4x-3/2=-3/4
4x=3/4
Turn the denominator to 16 by 4 and also multiply the top by 4 which becomes 12/16.
Divide the 12 by 4 and you get 3/16 which is the answer.
