Answer: Option 'C' is correct.

Step-by-step explanation:

Since we have given that

Height of trapezoid = 4 ft

Length of longer side=  'a' = 13 ft

Length of shorter side = 'b' = 9 ft

Due to height of 4 meter there will be right angle triangle at the corners.

In right angled triangle:

H^2=B^2+P^2\\\\H^2=4^2+2^2\\\\H^2=16+4\\\\H^2=20\\\\H=\sqrt{20}\\\\H=2\sqrt{5}\ ft

Since it is isosceles trapezoid, then there two non parallel sides should be equal.

So, Perimeter of isosceles trapezoid is given by

13+9+2\sqrt{5}+2\sqrt{5}\\\\=22+4\sqrt{5}\\\\=30.94\ ft

Hence, option 'c' is correct.

Answer:

C

Step-by-step explanation:

The perimeter of a figure is found by adding the sides of all the figures. The figure has sides 13 and 9. Its height is 4 so each of those sides is about 4 feet. So the perimeter is 13+9+4+4 = 30

C is the best solution.

a circle is divided into 18 equal parts how many degrees is the angle for each part? how many degrees is the angle for 5 parts?
Ket [755]
There are 360 degrees in a circle, and we have 18 pieces, so we need to see how many times 18 goes into 360. We can find this out by dividing.

360/18=20

You can check this by multiplying 20 and 18 (it equals 360)!

So, each fraction of the circle will be 20 degrees.

If you take 5 of these 20 degree pieces, you'll need to multiply them by 20 to see how many degrees they'd be.

You need to multiply by 20 because each piece is 20 degrees, and we need to find how many degrees 5 pieces is. It's the same as doing
20+20+20+20+20! :)

20*5=100. 5 parts will be 100 degrees.


Hope I helped! :)

I HAVE ASKED THIS TWICE NOW YOU GUYS!! SOMEONE PLEASE HELP ME I REALLY NEED HELP PLEASE THIS IS A VERY IMPORTANT TEST I WILL GIV
lubasha [3.4K]
Ok so 12 in. = 1ft
210 in = 17.5 ft
35 in = about 2.9 ft
17.5/2.9 = approximately 6 ft.
I think the answer is 6 ft
At the same time 210/35 = 6, which would make the length 6 in., because area equals base times height, so you just divide, which would make it 1/2ft.
I would go with 6 in.
