Question

(ii) The length of a rectangle is 6 m less than three times its breadth. The
dimensions of the rectangle, if its perimeter is 148 m, are
(a) 54 m, 20 m
(b) 14 m, 40 m
(c) 54 m, 24 m
(d) 54 m, 14 m​

Answer 1

Answer:

54m,20m

Step-by-step explanation:

Let x and y be the length and breadth resp

by which we get 6=3y-x Equation (1)

and 148=2y+2x Equation (2)

by Equation (1) *2 we get 12=6y-2x

Adding equation (1) and (2)

We get y=20 same puttin on equation (1) get x=54 respctively.
