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 .
Julie has 6 crayons, Mark has seven times more than Julie. How many crayons does Mark have?
Two Geometric figures are similar if you can go from one to another only through rotation (spinning), translation(moving WITHOUT rotating), reflection (making a simetry) or scaling (like zooming)
When scaling, you have to scale both vertical and horizontal axis at the same rate (example, 2x, 7x or 0.3x)
As such, all squares are similar and so are all REGULAR poligons among each other (all equilateral triangles are similar, all regular pentagons, etc)
This gets a bit tricky if the polygons are not regular, but the principle remains the same. For example, if you have a triangle with sides measuring 2,5 and 4, it will be similar to a triangle with sides measuring 8, 20 and 16, because you have scaled it 4x, hence, it's internal angle remained the same.
