Question

The length of a rectangular fields is 100 m. If its perimeter is 300 m, what is its breadth?

Answer 1

Length of the rectangular field = 100 m
Perimeter of the rectangular field = 300 m
Perimeter of a rectangle = 2 (Length + Breadth)
Applying the above formula, we get:
Breadth of the rectangular field = $\frac{Perimeter}{2}-Length$ = $\frac{300}{2}-100$ = 150 $-$ 100 = 50 m
