Question

find the perimeter of the shaded region has shown in the given figure figure

Answer 1

In the given figure, triangle ABC is right angle triangle.

Hence by pythagoras theorem,

AB^2+BC^2=AC^2

Therefore, AC=5cm

Now according to figure,

AC=CD=DE=EF=5cm

Hence the perimeter of give figure would be,

AC+CD+DE+EF+FH+HA=5cm+5cm+5cm+5cm+10cm+10cm=40cm

Therefore, ANS = 40cm
