Question

the floor of a storage unit is 1.2 meters long and 4.2 meters wide. starting at the far left corner, isabella walks down the length, across the width, and then diagonally back to the far left corner. how far does isabella walk? if necessary, round to the nearest tenth. meters

Explanation:

Step1: Sum length and width

$1.2 + 4.2 = 5.4$

Step2: Calculate diagonal length

Use Pythagorean theorem: $d = \sqrt{1.2^2 + 4.2^2}$
$\sqrt{1.44 + 17.64} = \sqrt{19.08} \approx 4.4$

Step3: Total distance walked

$5.4 + 4.4 = 9.8$

Answer:

9.8 meters
