durrr i dunno i think a^2 + b^2 = c^2

OpenStudy (marigirl):

yes we can use pythagoras theorem and obtain a length of 5 for c

how tf do yo uget 5 :( i only get 18.4

OpenStudy (marigirl):

if the green square has an area of 9, then each side length is 3 if the red square has an area of 16, then each side length is 4 then use this information a=3 and b=4 to figure out a^2 + b^2 = c^2 3^2+4^2=5^2 threforre SIDE lenght is 5

OpenStudy (marigirl):

side length of yellow square is 5 and the area is 25ft^2

OpenStudy (anonymous):
