Question

Answer the question attached below

Answer 1

Step-by-step explanation:

perimeter of fig = 3(2πr∅/360)+2r

= 3(2×3.14×10×90/360)+2×10

=3(2×31.4×1/4)+20

= 3×15.7+20

= 47.1+20

= 67.1

hence perimeter of fig is 67.1cm

area of fig = 3πr²

= 3×3.14×10²

= 9.42×100

= 942

hence area of fig. is 942cm²
