Width = w
Length = 5w
Given,
Perimeter = 276 ft
5w * w = 276
w² = 55.2
--- w = 7.429670248402684 ≈ 7.43 ft
--- l = 5w = 5*7.43 = <span>37.14835124201342 </span>≈ 37.15 ft

Answer:
66.3
Step-by-step explanation:
First, you need to find the 25% of $88.40.
88.40×25% (or) 25/100 = □/88.40
Solve that and you should get 22.10.
22.10 is 25% of $88.40
Finally, subtract your percent from original price and boom!
88.40 - 22.10 = $66.30
To prove it, you can use the Pythagorean theorem and plug in the numbers. If it equals the same number on both sides it is a Pythagorean triple.
a² + b² = c² (c is the hypotenuse or the longest side/length)
77² + 420² = 427²
5929 + 176400 = 182329
182329 = 182329
It is a Pythagorean triple
70% of 14
10%=14/10=1.4
70%=1.4x7=9.8
