Step-by-step explanation:
THUS,
WE CAN DIVIDE THIS FIGURE INTO TWO SECTIONS :
SECTION - 1 : RECTANGLE
SECTION - 2 : QUARTER CIRCLE
PERIMETER OF RECTANGLE = 2(L+B) - R = 11CM
= 2 * (2+20) -11
= 2 * 22 -11
= 44 -11
= 33 CM
PERIMETER OF QUARTER CIRCLE = (2 PI R) / 4 (- R)
= (2 * 22/7 * 11) / 4 (- 11)
= (44/7 * 11) / 4 (-11)
= 44/7 *11 * 1/4 -11
= 121/7 -11
= 110/7
= 15.71 CM
PERIMETER OF GIVEN FIGURE = 33CM + 15.71CM
= 48.71CM
