Answer 2

Answer:

45m

Step-by-step explanation:

length of the arc=¤/360 *2πr

so here ¤=90

so length of the arc = (90/360)*2*22/7*6.3

=( 1/4)*2*22/7*6.3

here there were two sectors of equal radii and angle so

lengths of the arc = 2*(1/4)*2*22/7*6.3=22*0.9= 19.8cm

now we know the length of arc

and additionally we have four radius so

4*6.3=25.2

so perimeter =25.2+19.8=45m
