Question

The Length Of a rectangular plot is 6m less than thrice it's breadth. Find the dimensions of the plot if it's perimeter is 148 m.

Pls answer it it's urgent...​

Answer 1

Answer:

20m

Step-by-step explanation:

perimeter  is = 148m

let breadth be= x m

then length= [3x-6] m

its a rectangle then perimeter= 2[l+b]

148 =  2{ 3x-6   +     x}

148 =  2[4x-6]

148/2=4x-6

74+6=4x

80/4=x

20m=x
