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:

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

1 . The lengths of the legs of a right triangle are 25 cm and 60 cm. What is the length of the hypotenuse?

Svetlanka [38]

$a^{2}+ b^{2} = c^{2}$ that is, hypotenuse.
Therefore, let the length of the hypotenuse be 'x.'
$25^{2}+ 60^{2}= x^{2}$
625+3600= $x^{2}$
4225= $x^{2}$
Therefore,
$\sqrt{4225}$ =x
65=x
The length of the hypotenuse is B.65 centimetres.
