Answer 1

Explanation:

1. The dimensions are 10 cm and 70cm

that means the length and breadth are 10cm and 70 cm respectively.

$the \: perimeter \: of \: the \: rectangle \: = 2(length + breadth)$

$2(10 + 70)$

$2 \times 80$

$160cm$

The perimeter of the rectangle is 160cm.

2. First we have to find the perimeter of the rectangular plot .

$the \: perimeter \: of \: the \: rectangular \: plot \: = 2(length + breadth)$

$2(120 + 90)$

$2 \times 210$

$420 \: m$

$now \: we \: have \: to \: find \: the \: number \: of \: trees \:$

$420 \div 6$

$70$

70 tress should be planted are a distance of 6 m.
