Zackery Yu · Answer 1

This is a great place to apply the Pyth. Theorem. Let the width be W.

Then W^2 + 28^2 = 35^2.

Solving this, we get W^2 = 441. Taking the positive square root, we get

W = 21 ft

21, I used Pythagorean Therom: a^2 + b^2 = c^2

a=28 b=? c=35

25^2 + b^2 = 35^2

Evaluate exponents

784 + b^2 = 1225

-784 - 784

b^2=441

Take square root of both sides.

b=21
