Answer:
50 square units .
Step-by-step explanation:
Given :
Image of letter E with height of 12 and width of 10
inside space of height of 5 and width of 7
To find : Area
Solution :
First calculate the area of rectangle ABKL = length *width = 12*10 = 120 square units
Now subtract the area of rectangle CDFE and HGJI from the rectangle ABKL to get the area of given figure
Area of CDEF = Area of HGJI since the length and width of the rectangles is smae
Thus Area of CDEF = length *width =5*7 = 35 square units
Thus the Area of HGJI = 35 square units
Now subtract the area of both rectangles from the area of ABKL
⇒120-(35+35)= 50 square units .
Thus the area of given figure LETTER E = 50 square units .
