The perimeter of a rectangle is 84cm.
Tatiana [17]

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>.

Hope this helps.

What is the area in terms of pi
ololo11 [35]

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:

C=\pi d

d - diameter

We have d = 70 cm. Substitute:

C=70\pi\ cm

The area of given figure is equal to the area of rectangle 70cm × 35cm.

(look at the picture).

The area of a rectangle:

A=(70)(35)=2,450\ cm^2
