Answer:
39 cm
Step-by-step explanation:
The perimeter of a rectangle is given as 2 (w + l) or 2w + 2l, where w and l are the sides.
Let us use <em>w</em> as 3 cm.
The perimeter of the rectangle is 2(3) + 2l = 6 + 2l
6 + 2l = 84 cm
We move the 6 to the left hand side and it goes from positive to negative.
2l = 84 - 6cm
2l = 78 cm
Divide both sides by 2.
l = 39 cm
There you have the answer for side <em>l</em>.

Answer:
<h2>C = 70π cm</h2><h2>A = 2,450 cm²</h2>
Step-by-step explanation:
The perimeter of the given figure is equal to the circumference of whole circle.
The formula of a circumference of a circle:

d - diameter
We have d = 70 cm. Substitute:

The area of given figure is equal to the area of rectangle 70cm × 35cm.
(look at the picture).
The area of a rectangle:

Our three consecutive odd numbers are x, x + 2 and x + 4.
Their sum is -51.
x + x + 2 + x + 4 = -51
You finish.
18 yards.
