3k+14=k. Subtract 3k from both sides. 14= -2k. Divide both sides by -2. K=14/(-2)=-7. K is -7.
Answer:
24 square inches
Step-by-step explanation:
We are given Image of letter E with height of 12 and width of 7
Inside space of height of 5 and width of 6
Initially calculate the area of rectangle ABKL = length *width = 12*7= 84 square inches
Now to get the area of given figure subtract the area of rectangle CDFE and HGJI from the rectangle ABKL
Area of CDEF = Area of HGJI because the length and width of the rectangles is same
Thus Area of CDEF = length *width =5*6 = 30 square inches
Thus the Area of HGJI = 30 square inches
Now subtract the area of both rectangles from the area of rectangle ABKL
⇒84-(30+30)
= 24 square inches .
Hence the area of given figure LETTER E = 24 square inches .
