Step-by-step explanation:
<em>1) The above problem can be broken in 2 parts, rectangle with 3 sides and a semicircle.</em>
The perimeter can be given as, for rectangle,
=
The perimeter of semicircle can be given by,
=
Thus, the total perimeter is =
The area can be found as, for rectangle,
=
for semicircle,
=
Thus, the total area is =
2)<em> This figure can be broken into semicircle and triangle with one side open.</em>
The perimeter is given by, of triangle,
=
of semicircle,
=
Thus, the total perimeter is =
The, total area is given by,
A = area of triangle + area of semicircle
A =
