i got 9/4 for the area of the triangle 1/2(1.5*3)

where your base is from -1 to 1.5 so that would be 2.5 then your height is 4

can you take a pic of the problem i need something more precise than the drawing

this is it..but i need to get the area from the graph at the bottom of this site... https://www.symbolab.com/solver/trigonometric-equation-calculator/%5Cint_%7B-1%7D%5E%7B2%7D%5Cleft%7C2x-3%5Cright%7C%20/?origin=enterkey

well i know the b= 2.5 1/2 (2.5) ( h) , my height looks like its greater than 4 and a little past 5 now that you gave the graph we can see that when x is -1 the function has a value of 5 which will be our height 1/2(2.5) (5) 12.5 /2

The smaller triangle has a base of 1 and a height of 1 1/2(1)(1)= Area of the big triangle and the smaller one =1/2 +12.5/2 =13.5/2

  • LynFran
ok continue im getting that..

  • anonymous
actually I'm looking at the attachment you sent. Do you see that the smaller triangle actually starts at 1.5 and ends at 2. so our base is actually .5 and our height is 1 1/2(1/2) (1) = 1/4 So now we know the 2 areas of the triangle and we can add them 12.5/2 + 1/4 25/4 +1/4 26/4 13/2
