Answer 1

Answer:

8.3 units

Step-by-step explanation:

Refer to the notations above, we can use Pythagoras Theorem to find the hypotenuse of the red triangle on the base of the prism.

The hypotenuse of the red triangle

$= \sqrt{ {7}^{2} + {4}^{2} }$

$= \sqrt{65}$

The hypotenuse of the red triangle is the common side of the yellow triangle's base.

d is equal to the hypotenuse of the yellow triangle.

The length of d

$= \sqrt{ { \sqrt{65} }^{2} + {2}^{2} }$

$= \sqrt{65 + 4}$

$= \sqrt{69}$

$= 8.30662...$

= 8.3 units
