Are the rectangles similar?

anonymous · Answer

well not really but on top of the smaller triangle it says A=2ft squared. yes the triangles are similar

mathstudent55 · Answer

Then 2 ft is the side and 2 ft^2 is the area?

anonymous · Answer

that doesn't make sense .

anonymous · Answer

i dont think thats the area because my book says that im suppose to find the area.

anonymous · Answer

You better attached exactly the question here.I can come with better solution.

mathstudent55 · Answer

If the smaller triangle has a side of 2 ft and an area of 2 ft^2, then the other side of the smaller triangle is 1 ft, since A = LW = (2 ft)(1 ft) = 2 ft^2
Since the triangles are similar, then since the ratio of the lenths of the sides is 5/2 = 2.5:1, then since the other side of the small triangle is 1 ft, then the other side of the larger triangle is 2.5 ft.
