Copper is a good conductor of heat.

That's why it’s used in cooking utensils and electrical wiring.

Wood, plastic, and glass are poor conductors (insulators), meaning they do not transfer heat easily.

Explanation

Let's denote the width as w and the length as 3w (since the length is thrice the width).

The area of the window is:

w × 3w = 3w²

Given area = 18.75 sqm

3w² = 18.75

w² = 18.75 / 3

w² = 6.25

w = √6.25

w = 2.5

Length = 3w

= 3 × 2.5

= 7.5
