A = 180 - 36 = 144
b = 360 - (113 + 36 + 144)
b = 60 -293
b = 67
Based on the given, there are two ways to know the dimensions of the rectangle. First, by simply drawing the coordinates given in a cartesian coordinate plane, P1(0,6),P2(8,6) by looking at the ordinate the length is 6 units, thru P3 (0,0) and P4 (8,0) and looking at the abscissa, the width is 8 units. The second way is through the distance formula, d=sqrt (X2-X1)2+(Y2-Y1)2. The dimensions are L=8 and W=6
So the area of one triangle is (3.5 x 9 ) 31.5 , times that by 4 gives us 126 , now add that to 7 squared which is 126 + 49 . the answer is 175 cm^2<span />
The 'V' one, because it's just a linear x = y with no negative y values, so it goes back up into a 'V'.
