Question

The length and breadth of a rectangular garden are 100m and 80m.Find the lenght of the wire needed to fence all round the garden five times

Answer 1

Solutions :-

Given :
The length and breadth of a rectangular garden are 100 m and 80 m respectively.

Find the perimeter of rectangular garden :-

Perimeter of rectangle = 2(Length + Breadth)
= 2(100 + 80) m
= 2 × 180 m
= 360 m

Find the length of the wire needed to fence all round the garden five times :-

Length of wire = (360 × 5) m
= 1800 m

Hence,
The length of the wire needed to fence all round the garden five times = 1800 m

Answer 2

Solutions :-

We have,
Length of rectangular garden = 100 m
Breadth = 80 m

Perimeter of rectangular garden = 2(Length + Breadth)
= 2 (100 + 80) m
= 200 + 160 m
= 360 m


Length of wire = 5 × Perimeter of rectangular garden
= 5 × 360 m
= 1800 m


Answer : Length of wire = 1800 m
