The height of the triangle is 15in and the triangle base is 6in Monica says that the area of fabric is 90in squared what error did monica make explain your answer

Respuesta :

monica multiplied 15 by 6 and got 90 but didnt divide it by 2 to get 45 
Monica multiplied 15 by 6 which is incorrect because when finding the area you must multiply the base time height times 1/2
so 1/2 x 15 x 6= 45
