Start with the area of base Can you calculate it? If not can you identify the base and the height?

OpenStudy (mythorius):

Base A = 72?

OpenStudy (faiqraees):

72 or 12?

OpenStudy (mythorius):

1/2(144) = 72

OpenStudy (haleyelizabeth2017):

@FaiqRaees it is 72.... 1/2*(12*12).

OpenStudy (faiqraees):

correct now use 1/2bh to find the area Multiply that by 3 to get the area of 3 triangles Add the area with the base area

OpenStudy (mythorius):

216 @FaiqRaees

OpenStudy (faiqraees):

Total area = Base Area + 3(triangle area) T.A. = 72+ 3(0.5*6*8) Evaluate

OpenStudy (mythorius):

144
