Answer 1

There are 10 triangles, out of which 5 of black and 5 of grey color. Now,

Area of of each cloth=5× area of 1 triangle

Area of triangle=

√s(s−a)(s−b)(s−c) ,

s=a+b+c/2 = 50+20+50/2

s=60㎝

∴ar△=√60(60−50)(60−20)(60−50)

=√60×10×40×10

=√6×10×10×4×10×10

=2×10×10√6=200√6㎠

Area of each cloth required

=(5×200√6)㎠.

=1000√6㎠
