Question

question : find the area and
perimetre of the following figures
all angles are 90degree and all sides are centimetre
pls answer this question

Answer 1

36 perimeter and 38 sq cm area

Answer 2

from the topmost corner of L name all the points clockwise, A, B ,C, D ,E, 

Length of BC= 10-3 cm =7 cm 
 length of CD = 8-2 cm = 6 cm 
therefore, perimeter = AB+BC+CD+DE+EF+FA = 2+7+6+3+8+10= 36 cm.
 
extent CD to meet it on AF at point. T.
Therefore, area of rect. ABCT= L X B= 7 X 2 = 14 cm.
                   area of rect. TDEF =  L X B = 8 X 3 = 24 cm
 
Total area of the figure = area of rect. ABCT = area of rect. TDEF
                                      = 14 + 24 =38 cm sq.
