Question

find the area and perimeter of the following figures all the angles are are 90 degrees and all the sides are in cm

Answer 1

Perimeter :

= 10+2+(10-3)+(8-2)+3+8
= 12+7+6+3+8
= 36 units
---------------------------------
Area :

= (10×2) + [(8-2)×3]
= 20+(6×3)
= 20+18
= 38 unit ²

Answer 2

consider base rectangle,
area = 3*8 = 24cm^2
now consider that vertical rectangle leaving that one block because we have already found its areA
so u will get,
area = 7*2 = 14
so total area = 38
