Question

Find the area and perimeter of the shaded part in each of the following figures.

Answer 1

REF.IMAGE

$Perimeter=2+8+8+2.5+2.5+1.5+16+1+16+4.5+2.5+2.5$

$=67m$

$Area=2\times 18+(7\times 2.5)+1\times 16$

$=69.5m^2$

$Perimeter=7+2+4+2+4+6+2+(2+4+2+6)$

$Perimeter=41m$

$Area=7\times 2+12\times 2+4\times 2$

$Area=46m^2$
