Area of canvas used in stitching = total area of canvas
Total area of canvas $$= 7656/7$$ + total area of canvas/10
Total area of canvas – Total area of canvas/10$$= 7656/10$$
Total area of canvas$$(1 – \dfrac1{10}) = \dfrac{7656}7$$
Total area of canvas$$\times \dfrac9{10} = \dfrac{7656}7$$
Total area of canvas$$= \dfrac{7656}7 \times \dfrac{10}9 = \dfrac{76560}{63}$$
Therefore, the total area of canvas$$= 1215.23\,m^2$$
