board of length 4 m and breadth 2.5 m at the rate of
120 per m.​

Answer 1

Answer:

Rs 1560

Step-by-step explanation:

Length = 4 m

Breadth = 2.5 m

Perimeter of rectangular board = 2(length + breadth)

= 2(4 + 2.5)

= 2 × 6.5

= 13 m

Cost of painting border of rectangular board = 120 × 13

= Rs 1560
