WHAT IS THE QUESTION?

I need to know the surface area of this shape

Sophie [7]

The area is the area of 2 pairs of congruent triangles and one rectangle. Use the formulas for the areas of these figures, then add results.

Front triangle area (A = (1/2)bh)
.. = (1/2)(16 m)*(25 m) = 200 m^2

Right side triangle
.. = (1/2)(22 m)*(24 m) = 264 m^2

Base (A = lw)
.. = (16 m)*(22 m) = 352 m^2

Total area
.. 2*front triangle +2*side triangle +base
.. = 2*200 m^2 +2*264 m^2 +352 m^2
.. = 1280 m^2

What are three rational numbers between -1 and -2

MArishka [77]

well, rational = fractional, namely something you can write as a fraction, well, anything between -1 and -2 is just less than -1 so

$\bf \boxed{-2}\dotfill \stackrel{-1-\frac{1}{4}}{-\cfrac{5}{4}}\dotfill\stackrel{-1-\frac{1}{10}}{-\cfrac{11}{10}}\dotfill \stackrel{-1-\frac{1}{99}}{-\cfrac{100}{99}}\dotfill \boxed{-1}$
