Answer 2

Given,

Dimensions of a triangle

Cost of lace per $10$ cm

To find,

Cost of lace border

Solution,

The cost of lace for making $250 cm$ is $Rs.375$

Let us assume the triangle scarf to be denoted by A

Sides of A $= 70, 80, 1$ m

Converting $1$ m into cm

$1m = 100cm$

The Perimeter of A = S + S + S cm

                               = $80 + 70 + 100$ cms

                               $= 250 cms$

Cost of lace per $10cm = Rs.15$

Cost of lace per cm $= 15 / 10 Rs.$

Therefore, the cost of lace for $250cm = 250$ ×$\frac{15}{10}$ Rs.

                                                           $= 25$ × $15$ Rs

                                                           $= Rs.375$

Therefore, the cost of lace for making $250 cm$ is $Rs.375$
