11x5 m is 32m
64 m2 perimeter_of_square = 4 x side_length ⇒ side_length = perimeter_of_square ÷ 4 area_of_square = side_length2 Thus if perimeter is 32 m: side_length = 32 m ÷ 4 = 8 m ⇒ area = (8 m)2 = 64 m2
to find a perimeter of a triangle you need the add the lengths of the sides. So in this case, the sides are 18 + 32 + 252 so the answer would be 302meters Just a little hint : keep in mind what the measurements are in (i.e. centimeters, meters...) . you might to convert for some problems.
It is: 32/4 = 8m in length
