Answer 1

Answer:

100$\sqrt{6}$ cm²

Step-by-step explanation:

b = 20 cm, a = 50 cm

h = $\sqrt{a^{2}-(\frac{b}{2})^{2} }$

= $\sqrt{50^{2}-(\frac{20}{2})^{2} }$

= $\sqrt{2500-100}$

= $\sqrt{2400}$

= 20$\sqrt{6}$ cm

∴ Area of each piece = $\frac{1}{2}$ × bh

= $\frac{1}{2}$ × 20 × 20$\sqrt{6}$

= 200$\sqrt{6}$ cm²

Total cloth used = 200$\sqrt{6}$ × 10

= 2000$\sqrt{6}$ cm²

Area of each coloured cloth = $\frac{2000\sqrt{6} }{2}$

= 1000$\sqrt{6}$ cm²
