Helppp please and thank you !

209 (Sorry if wrong)

Step-by-step explanation:

12x12=144

13x5=65

144+65=209

How to get that

We have a 12 by 12 square of area 12*12 = 144 square meters.

Then on top of this we have a triangle with base 12 and height 5, so its area is base*height/2 = 12*5/2 = 60/2 = 30 square meters

Overall, the two areas combine to 144+30 = 174 square meters

Side notes:

answer: your answer is a

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
