Answer:
GIVEN :- sum of circumference + radius = 153 cm
======> 2πr + r = 153
=======> r(2π+1) = 153
======> 2π+1 = 153/r
=======> 2×22/7 + 1 = 153/r
=======> 44/7+1 = 153/r
=======> 44+7/7 = 153/r
=====> 51/7 = 153/r
reversing both sides
====> 7/51 = r/153
===> 7×153/51 = r
==> 7× 3 = r
==> 21 = r
circumference of circle = 2πr
===> 2×22/7×21
===> 2×22×3 ==> 132 m
AREA OF CIRCLE = πr²
==> 22/7×7×7
==> 22×7 ==> 154 m²
