with lace. If the lace costs Rs 10 per cm then the cost of the lace
border is ________

Answer 1

Answer:

Rs 2350

Step-by-step explanation:

The lace is bordered on the perimeter of the triangular scarf.

Perimeter of scarf = (60 + 75 + 100) cm = 235 cm

Cost of lace = Rs 10 per cm

Total cost = 235 × 10 = Rs 2350

Answer 2

Answer:

Rs 2350

Step-by-step explanation:

Sides of triangel

a = 60cm

b = 75cm

c = 1m = 100cm

Perimeter of triangular scarf

= sum of all sides

= a + b + c

= 60cm + 75cm + 100cm

= 235cm

Cost = Rate × Perimeter = 10 × 235 = Rs2350
