Question

A 1.5 m square window is to be fitted with a net on wooden strips nailed to the window frame. What is the total length of the wooden strips required?

Answer 1

The length of the side of the square window = 1.5 m
The wooden strips are nailed to the square window.
So, the length of the wooden strips will be equal to the perimeter of the square window.
Perimeter of square window = 4 × side
= (4 × 1.5) m
= 6 m
Hence, the total length of wooden strips required will be 6 m.
