Question

On a rectangular table cloth of area 6.25 sq. meters, four rectangular patterns have been embroidered. If the dimension of the pattern are $25cm\times 20cm$ each, find the remaining area of the table cloth.

Answer 1

Assuming the dimensions of the embroidered patterns are $20cm\times 25cm$, then the $4$ patterns cover $=4\times 20\times 25=2000$ sq cm or $\frac{2000}{10000}=0.2$sq m. If the cloth has an area $=6.25$sq m, the area of the cloth without the embroidery patterns is $=6.25-0.2=6.05$sq m.
