To find the area of this shape you must first find the area of the rectangle 8 x 13 = 104. Once you find the area of the rectangle you must then find the area of the triangle which is base x height divided by 2. So to find the base of the triangle you must add the 4s on the bottom and subtract it by 13. So 13-8=5 so the base of the triangle is 5, the height is 6 and 5x6 is 30. You then divide it by 2 so you get 15. Now you take the area of the rectangle,104 and subtract it by the area of the triangle, 15. The answer is 89. I hope this helps.
With this problem you just look at the graph and answer it that way. Look at where the heart rate is at its max and then look at the beginning and end, the shape of the graph. Then answer the question.
3 1/2
2 1/4+ 1 1/4 = 3 2/4
or 3 1/2
