4. 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 4. In the figure below two congruent squares touch at one corner. One side of the square measures 5 cm.

62.5 cm^2

62.5

how did u guys get that? -confused-

OpenStudy (anonymous):

Area of two squares = 50cm^2 (25 + 25) Area of triangle = (1/2) *base * height (1/2) * 5*5 = 12.5 cm^2 and you need not mention to find the area to nearest tenth, because it comes only in one decimal.

OpenStudy (anonymous):

so how did you get 65.2?

OpenStudy (anonymous):

It's 62.5

OpenStudy (hoblos):

it is 62.5

OpenStudy (anonymous):

And even you can take the area of triangle to be half of the area of square

sorry 62.5... i still dont understand ur equation says 12.5

OpenStudy (anonymous):

Area of triangle = (1/2) * base * height That is equal to 25/2 which is 12.5

OpenStudy (anonymous):

so where does the 62.5 come in :'( im so sorry i dont ubderstand

OpenStudy (anonymous):

area of sq is 50cm^2 and area of triangle is 12.5 So whole area is 50+12.5 =62.5

OpenStudy (anonymous):

omg i feel so stupid than k uu

OpenStudy (anonymous):

It's good to clear doubts

OpenStudy (anonymous):

thank u
