Answer 1

Answer:

100√6 cm^2

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)

s = 50+20+50/2

= 60

area = √60(60-50)(60-20)(60-50)

=200√6 cm^2

area of each cloth= 5(200√6)cm^2

=1000√6 cm^2

that is the answer. The formulas are there in the b
