Answer:
Step-by-step explanation:
Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.
Answer:
b>-18
Step-by-step explanation:
inequality form:b>-18
interval notation:(-18,inf.)
Step-by-step explanation:
(o, -2) is the correct answer because in -90°
P [x,y] =P' [y,-x ]
hope it is helpful to you
For trapezoid, the area = (upper base + lower base) * height / 2
So area = (12 + (2*2 + 12) ) *13 / 2 = 182
