Question

the length of rectangle plot is 6 m less than thrice its breadht find the dimension of plot if the perimeter is 148

Answer 1

hyy, mate i give u answer wait....

let the breadth of rectangle is x
and length =3x-6

so. perimeter of rectangle =2(l+b)
148=2(3x-6+x)
148=2(4x-6)
148=8x-12
148+12=8x
160=8x
x=160/8
x=20

so breadth =20m
length =3x-6=3*20-6=60-6=54m

hope it will help you

Answer 2

SOLUTION

Let the width of the rectangle= x m

Let the width of the rectangle= x mNow, length of the rectangle= (3x-6)m

=)Now, Perimeter= 148m (Given)

=) 2(length+breadth)= 148

=) length+ breadth= 74

=) 3x-6+ x= 74

=) 4x= 74+6

=) 4x= 80

=) x= 80/4

=) x= 20

• Now, breadth= 20m
• Length= 3× 20-6 = 60-6 = 54m

hope it helps ☺️
