While selling clothes for making flag A shopkeeper claims to sell each piece of cloth in a shape of a equilateral triangle of side 10cm while he was actually selling the same in the piece of isosceles triangle with side 10 cm, 10 cm and 8 cm how much cloth will he save in selling each flag ​

i Hope ur ans in 100

he will save 2cm cloth in each flag

step by step explanation:

a=10 cm \\ b=10 cm\\ c=8 cm\\ \frac{a+b+c}{2} = s\\ \\ \frac{10+10+8}{2} \\ \\ \sqrt{S (s-a)(s-b)(s-c)}\\ \sqrt{14 (14-10)(14-10)(14-8)

14 , 4 , 4 and 6 will cut down by simplifying

8\sqrt{21}

8 × 4.58 = 36.64 cm^{2} = Area of isosceles triangle

But the shopkeeper claims to sell the cloth in the shape of an equilateral triangle whose sides are 10 cm each

∴ Area of equilateral triangle = \sqrt{\frac{3}{4} × 10^{2}

25\sqrt{3} = 25 × 1.73

= 43.25 cm ^{2}

hence, the area of the cloth he was saving =

Area of equilateral triangle - area of isosceles triangle

= 43.25 - 36.64

= 6.61 cm^{2}

6.61 cm^2

Step-by-step explanation:

Fake Area = 68 cm²

Using Heron's Formula:

Real Area = √20(20-8)(20-15)(20-17)

Real Area = √(20×12×5×3)

Real Area = √(60×60)

Real Area = √60×60

Real Area = 60 cm²

∴ He saves 8 cm² of cloth

In 200 flags he will save 1600 cm² of cloth.

∴ He will save 1600 cm² × 4 = ₹6400

Hope it Helps :)
