Step-by-step explanation:
we have that general formula area of the triangle is √s(s-a)(s-b)(s-c)
where S=a+b+c÷2
here 50+50+20÷2=120÷2=60
There fore S=60,
=√60(60-50)(60-50)(60-20)
=√240000
=100√24
here they asked cloth required to make umberlla
for one triangle we got cloth required is
=100√24
for total umberlla =12×100√24
there fore 1200√24 (cm)2 cloth is required
