Question

pls send the proper solution​

Answer 1

ab is 60cm

ac is 60cm

bc is 60cm(base)

as equilateral triangle so all sides are equal.

so now,

lets find out the area of the whole triangle(ABC)....

Area= 12×base×height

=12×60×60

=43200 cm²

if G is the centroid then BG is 60cm/2(half of 60cm)= 30cm.

BG=GC=30cm

BC=60cm

Now, lets find out the area of triangle(GBC)...

Area= 12×base×heighe

= 12×60×30

= 21600cm²

Now, area of the shaded portion=triangle(ABC-GBC)

=(43200-21600)cm²

=21600cm²

Hope it helps...

Have a great day
