There are four fruit trees in the corners of a square backyard with 30ft sides. what is the diagonal distance between two of the apple trees to the nearest tenth? a)42.4ft b)42.3ft c)30.0ft d)30.3

i do believe it is c 30.0ft

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
