Length of lines AD and BC is 5 ft
Length of lines AB and CD is 7.81 ft
The answer is C 25.62 ft
How you get that:
Count the number of boxes between A and D. (because it is slanted you use the length going down/up and the length going right/left)
Down: 3
Right: 4
use Pythagorean Theorem (a^2 + b^2 = c^2)
3 squared is 9
4 squared is 16
9 + 16 = 25
square root of 25 is 5
BC has the same length
count boxes between A and B
Up: 6
Left: 5
6 squared is 36
5 squared is 25
36 + 25 = 61
square root of 61 is 7.8102496759
round to nearest hundreth (7.81)
CD has the same length
add it together
5 + 5 + 7.81 + 7.81 = 25.62
