the length and breadth of a rectangle rlgram are 70 m and 50 m inside it and all along the edges there is road of width 2 m .Find the area of the road.​

Answer 1

$are a\: of \: rectangular \: rlgram \: = \: 70 \times 50 \\ = > 3500 \: {m}^{2}$

$area \: of \: internal \: rectangular \: rlgram = 46 \times 66 \\ = > 3036 \: {m}^{2}$

$area \: of \: road \: = 3500 \: {m}^{2} - 3036 \: {m}^{2} \\ = > 464$
