In the figure below two congruent squares touch at one corner. One side of the square measures 5 cm. The triangle created from two of the common sides is a right triangle. Find the area (to the nearest tenth) of the entire figure.

That implies that the triangle right there is half the area of the blue square; |dw:1342568064118:dw|

OpenStudy (zepp):

|dw:1342568099324:dw| And if we separate each square into two triangles, then you'll get 5 congruent triangles.

OpenStudy (zepp):

Each triangle has height 5, base 5\[\large \frac{bh}{2}=\frac{5*5}{2}\] We have 5 triangles, therefore \(\huge \frac{5*5}{2}*5=\frac{5^3}{2}\)

OpenStudy (ledah):

o_o oh

OpenStudy (ledah):

was that all there was to it?

OpenStudy (zepp):

Yeah

OpenStudy (ledah):
