A circle and a rectangle have the same perimeter. The sides
of the rectangle are 18 cm and 26 cm. What will be the area
of the circle?
(a) 88 cm2
(b) 1250 cm2
(c) 154 cm2
(d) 128 cm2
(e) None of these
Answer Posted / suchi teegala
perimeter of rectangle = 2(l+b)
given l abd b as 18 cm and 26 cm
therefore perimeter of rectangle = 2(44)
perimeter of circle = 2*pi*r
given 2*pi*r=2(l+B)
i.e, 2*(22/7)*r= 2(44)
(22/7)*r=44
r=14 cms
area of the circle = pi*r*r
=(22/7)*14*14
=616 sqcm is the answer
