Question

If the length of a rectangular field is 7/2 of its breadth and its perimeter is 99 m, find the length and breadth of the field.

Answer 1

Let breadth be x,

So,length = 7x/2




Given that perimeter = 99


2(length + breadth) = 99

2(x + 7x/2) = 99

2x + 7x = 99

9x = 99

x = 11



Hence, breadth = x = 11 m
Length = 7(11)/2 = 77/2 = 38.5 m

Answer 2

the length is 77m and breadth is 22m
as, if we take the breadthas x so
length=7/2 x
7/2x +x = 99m
9/2 x = 99m
9x = 198m
x = 198/9
x=22
hence, 22 X 7/2 = 77m = lenght
and breadth = 22m
