Please please please help
I know it’s not worth a lot of points but I really need help



Find the total area of khiannas fish. Make use of symmetry and repeated calculations to simplify the problem. Include all of you work in your response






Part 2: constrict an image of an animal of your choosing ( something other than a fish) completely out of triangles and right triangles. Make sure that your image consists of at least eight shaped. At lest one of your shapes must be a rectangle and at least must be a right triangle.
Measure the sides of the individual shaped and find the total area of the composite figure.
Be sure to include in your response
• the “ animal” image you have created
• the computation you preformed finding the areas of the animals composite parts
• the total area of the figure

Answer 1

The triangle in the front has base $2+2$ and height $4.5$ so area $\frac 1 2(2+2)(4.5)$

The top fin is $\frac 1 2(2.25+0.75)(3)$

The back fin is $\frac 1 2(4.5)(3+5)$

The bottom fin $\frac 1 2 (1+.5)(1)$

The back of the fish by the tail, $\frac 1 2 (2+2)(4.5)$

The four little triangles, $4 (\frac 1 2 )(.5)(1.5)$

Two thin rectangles, $2(.5)(5)$

One big rectangle  $(2+2)(1.5+5+1.5)$


Adding it all up

$\frac 1 2 ( (2+2)(4.5) + (2.25+0.75)(3)+ (4.5)(3+5)+(1+.5)(1)+(2+2)(4.5)+4(.5)(1.5)) +2(.5)(5)+(2+2)(1.5+5+1.5) = 122.5$

Probably a mistake in there somewhere; check it good.
