of
a
square
of
side
14cm
as
their


diameter.
Find
the
perimeter
of
the
given​

Answer 1

Answer:

144cm

Step-by-step explanation:

According to the figure , the side of the squares are also the base ( diameter ) of the semicircles .

So , diameter of a semicircle = 14cm

Radius = 7cm

Perimeter of the semicircles

= 4(πr + d)

= 4(22/7 × 7cm + 14cm)

= 4(22 + 14cm)

= 4 × 36cm

= 144cm
