The two triangles are similar by angle-angle test for similarity.
Ratio of sides = 12:24 = 1:2

Therefore, ratio of areas of two similar triangles
= (Ratio of sides)^2
= (1:2)^2
=1:4

Assuming area of smaller flowerbed to be x sq. m
Therefore, area of larger flowerbed = 4x sq. m

Rate of charge = Total cost / Area of field
= Rs. 5000/x per sq. m

Therefore, cost of flowering larger flowebed = Rate of charge * area of flowerbed
= 5000*4x/x
= Rs. 20,000
