Question

Answer 1

Step-by-step explanation:

Herons formula-

There are 10 triangles.

5 triangles of blue and 5 of grey.

area of each cloth= 5 * (area of 1 triangle)

area of triangle =  √s(s-a)(s-b)(s-c)

semi peri = 50+20+50/2

= 60

area = √60(60-50)(60-20)(60-50)

=√60×10×40×10

area = 2×5×2 √2×5×3

=20√30 CM

area of triangle=5×20√30

                          =100√30 CM²

∵AREA OF 10 TRIANGLES=10×100√30=1000√30 CM³

∴THE AREA OF CLOTH REQUIRED=1000√30 CM³
