Answer:8^4 + 14^36 is the perimeter because they are for sides in a rectangle so you have to double the amount.
Answer:
720.
Step-by-step explanation:
1*2*3*4 * 5*6
= 24 * 30
= 720.
Splitting it up in this way makes it easier.
I strongly recommend that you find an illustration of an ellipse that features the three distances a, b and c. You could Google "ellipse" and sort through the various illustrations that result, until you find the "right one."
There is an equation that relates a, b and c for an ellipse. It is a^2 = b^2 + c^2.
a is relatively easy to find. It is the distance from the center (0,0) of your ellipse to the right-hand vertex (20,0). So a = 20.
b is the distance from the center (0,0) of your ellipse to the right-hand focus (16,0). So b = 16. You could stop here, as it was your job to find b.
Or you could continue and find a also. a^2 =b^2 + c^2, so
here a^2 = 16^2 + 20^2. Solve this for a.
Answer:
length is 26 and width is 23
Step-by-step explanation:
let width be x
then length is 3+x since it is 3 more than the width
perimeter of a rectangle = 2l + 2w
98=2 [3+x] + 2x
98=6+2x+2x
98=6+4x
98-6=4x
92=4x
x=23
width is 23 and
breadth is 26
