Answer 2

Step-by-step explanation:

• Given :- perimeter = 150m
• let the breadth of rectangle be X
• so, length of rectangle = 2X
• Now, we know that,
• perimeter of rectangle = 2 ( l + b)

150 = 2 ( 2X + X )

150/2 = 3X

75 = 3X

X = 75/3 = 25m

• Length :- 2X = 2 × 25 = 50
• breadth :- X = 25

• Area of rectangle= length × Breadth
• = 50 × 25

= 1250 m²

Total cost of planting trees = 1250 × 20

= 25000
