perimeter = 25 + 2πr +25 cm

= 50 + 2 ×22/7 ×3.5

= 50 + 1

= 51 cm

area = (l × b )+( πr^2)

= (25 ×7) + (22/7 × 3.5^2)

= 175 + (38.5)

= 312.5 cm sq

parul7547: HEY I THINK THAT'S INCORRECT

nithiya26: wby???

parul7547: while calculating perimeter .....in step 3 you wrote 1 instead of 22.......and in area in the last step it will be 213.5

nithiya26: sry

nithiya26: it is a typing mistake
