a climber starts descending from 533 feet above sea level and keeps going until she reaches 10 feet below sea level how many feet did she descend

Distance from 533 to -10 is: 533 - (-10) = 533 + 10 = 543

Step-by-step explanation:

Divide the descent into two parts. 1st part: From 533 feet to sea level. 2nd part from sea level to 10 feet below sea level. Add the distance for each of the two parts. Hint: How many feet above or below sea level is sea level?

Step-by-step explanation:

area of ramp = 24 x 36= 864

area of side (square)= 24 x 24 = 576

area of 2-side (triangle)= 2 x (0.5 x 24 x 41.8) = 1003.2

total area to be painted = 864 + 576 + 1003.2 = 2443.2
