Question

Find the perimeter of the following figure AB=8 cm 8 BC=3cm CD=5cm DE=6cm​

Answer 1

Step-by-step explanation:

Area of the quadrilateral = area of the triangle ABD + area of the triangle DBC.

From Abcd BC power 2 =DC power 2-bd power2

[Using Pythagoras theorem]

⟹BC =13 2−12 2=25

BC= 25 =5 cm

Area of the ΔDBC=1/2xbxH

=

1/2×5×12

=30 CM 2
