Hi Softballgirl6! I would say that first, we could pretend that the zeros don't exist because we could add those in later. Then just working with 1x2x3x4, we could mentally solve this to 24 and then add in the extra 4 zeros that we left out at the beginning. This brings the answer to 240000. Hope this helps! :)

A football field is a rectangle 80 meters wide and 110 meters long. Coach Trevor asks his players to run from one corner to the
vladimir2022 [97]

Answer: the distance from one corner of the field to the other corner is 136 m

Step-by-step explanation:

The distance from one corner to the other corner is the diagonal and it

divides the field into two equal right angle triangles. The diagonal represents the hypotenuse of each right angle triangle. The length and width of the rectangle represents the adjacent and opposite sides of the right angle triangle. To determine the length of the diagonal, d, we would apply Pythagoras theorem which is expressed as

Hypotenuse² = opposite side² + adjacent side²

Therefore

d² = 110² + 80²

d² = 12100 + 6400 = 18500

d = √18500

d = 136 meters
