Answer 1

Answer:

Total area can be decorated with these colour papers​ is 4615 cm².

Step-by-step explanation:

Given:

Sides of the square of the color paper is 10 cm , 11 cm , 12 cm , 13 cm , 14 cm , 15 cm , 16 cm ,17 cm , 18 cm , 19 cm , 20 cm , 21 cm , 22 cm , 23 cm , 24 cm.

To find: total Area covered by color papers.

We know that,

Area of the Square = Side × Side

So,

Area of Square paper 1 = 10 × 10 = 100 cm²

Area of Square paper 2 = 11 × 11 = 121 cm²

Area of Square paper 3 = 12 × 12 = 144 cm²

Area of Square paper 4 = 13 × 13 = 169 cm²

Area of Square paper 5 = 14 × 14 = 196 cm²

Area of Square paper 6 = 15 × 15 = 225 cm²

Area of Square paper 7 = 16 × 16 = 256 cm²

Area of Square paper 8 = 17 × 17 = 289 cm²

Area of Square paper 9 = 18 × 18 = 324 cm²

Area of Square paper 10 = 19 × 19 = 361 cm²

Area of Square paper 11 = 20 × 20 = 400 cm²

Area of Square paper 12 = 21 × 21 = 441 cm²

Area of Square paper 13 = 22 × 22 = 484 cm²

Area of Square paper 14 = 23 × 23 = 529 cm²

Area of Square paper 15 = 24 × 24 = 576 cm²

Total Area = 100 + 121 + 144 + 169 + 196 + 225 + 256 +289 + 324 + 361 + 400 + 441 + 484 + 529 + 576 = 4615 cm²

Therefore, Total area can be decorated with these colour papers​ is 4615 cm².
