The length of the window is thrice its width. Find the length of the window when its area is 18.75 sqm?
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
