Question

the length of a rectangular field is 3 times its breadth if the perimeter of the field is 32 M find the length and breadth

Answer 1

Let the length = 3x
Let the breadth = x

P = 2(L + B)

32 = 2(3x + x)

32 = 2*4x

32 / 8 = x

x = 4

Length = 3x = 3*4 = 12

Breadth = x = 4


Thanks

Answer 2

a/q
l=3b
perimeter of field=32=2*l+b.
here
2*3b+b=32
2*4b=32
8b=32
b=4 .so l=3*4=12m
