A football field is a 64-meter-wide, 100-meter-long rectangle. What is the length of a diagonal of a football field to the nearest meter?

Question

pls help me

Answer 1

 

Draw yourself a picture of the field and label both widths (64m) and both lengths (100m).  

 

Then draw a diagonal.  (For example, you can connect upper left corner to lower right corner.)

 

Notice that the diagonal is the hypotenuse of a right triangle. (You have already labeled the two legs of the triangle.)   

 

Use the Pythagorean Theorem and try to work it from there.

Answer 2

The diagonal represents the hypotenuse of the right triangle.  The legs of the right triangle are the length and width of the field.

 

Use the Pythagorean theorem.

 

64² + 100² = (diagonal)²

 

 

Solve for diagonal.

Answer 3

Here is all the help you need.  (1) draw the rectangle (2) draw its diagonal [just one] (3) stare at the picture until you see a right triangle (4) use the Pythagorean Theorem.
