stepan [7]

Answer:

Step-by-step explanation:

1. To find the area of a semicircle the formula is

$A=\frac{\pi r^2}{2} \\=\frac{\pi 1^2}{2} \\=6.283m^2$

The square

$A=a^2=2^2=4m^2\\6.283+4=10.283m^2$

2. Triangle

$A=\frac{ab}{2} \\=\frac{6*2.5}{2} \\=7.5m^2\\7.5*2=15m^2$

Rectangle

$A=wl=8*13=104m^2$

$104-15=89m^2$

Semicircle

$A=\frac{\pi r^2}{2} \\=\frac{\pi 3^2}{2} \\\\=14.137m^2$

Square

$A=a^2=6^2=36$

$36-14.137=21.863m^2$

Answer:

Perimeter: 22cm Area: 24cm^2

Step-by-step explanation:

To find perimeter we add all the sides together. There are two missing sides in this picture.

The bottom one is found by adding the two top lines 4 + 2 = 6

The one on the right can be found by subtracting the left line and the given right line 5 - 2 = 3.

Now we have all the lines, add them together we get 22cm!

Now, there are two ways to find the area. Of course I’m going to show the one I prefer.

Imagine the chunk in the top right is not missing; what would the area of the rectangle be? 30cm^2

And now what’s the area of the missing chunk?

Our given line multiplied by the one we calculated for: 6cm^2

Now subtract the whole rectangle minus the piece we are missing 30 - 6 = 24cm^2
