Question

do this problem 5 plz

Answer 1

the perimeter of the figure=11+11+23+23=68cm
2)area=1/2*πr^2
=154/2=77
perimeter=πr+ diameter
=22+14=36
3) area= area of rectangle-area od semicircle
=(10×7)+-(1/2×πr^2)
=70-19.25
=50.75 cm^2
perimeter=perimeter of the semicircle+7+10+10
=πr+27
=11+27
=38 cm
