Answer:
18.87 units
Step-by-step explanation:
the estimated distance from a to d is the same as a to b. we can find the length of the diagonal using pythagoras' theorem:
a² + b² = c²
√(2² + 3²) = 3.6056 (to 5s.f.)
now, we can use the same method to calculate the distance between d and c, as well as c and b:
√(3² + 5²) = 5.8310 (to 5s.f.)
adding these values, we will get:
(3.6056 + 5.8310) × 2 = 18.87 units (to the nearest hundredth)
i hope this helps! :D
