Question

I need an answer you guys !! Please

Answer 1

First let's model the carpet as a rectangle.
 The diagonal of a rectangle is given by:
 d = root ((L) ^ 2 + (W) ^ 2)
 Where,
 L = long
 W = width.
 Clearing the width we have:
 d = root ((L) ^ 2 + (W) ^ 2)
 d ^ 2 = (L) ^ 2 + (W) ^ 2
 (W) ^ 2 = (d) ^ 2- (L) ^ 2
 W = root ((d) ^ 2- (L) ^ 2)
 Substituting the values
 W = root ((root (89)) ^ 2- (8) ^ 2) = 5
 answer
 The width of the carpet is
 5 feet
