Answer:
As the dimensions of the mat are 5 and 3.5
therefore it's area Will be 5×3.5=17.5
Now as the width of the border is 1.8
So, substract 1.8 from dimensions
Now the new dimension are 1.7and 3.2
And it's area Will be 1.7×3.2= 5.44
As the cost of mat is 272/m^2
therefore cost of 1 m will be 272÷17.5
and cost of 5.44 m ( border ) = 272÷175 × 5.44
That is 187.44
