Help me please and thank you :)

 A. 74 cm

Step-by-step explanation:

First, we break the rhombus down into similar shapes,

The area of 2 triangles = The area of a square

So we take the triangle from the left and combine it with the triangle on the right, it should make a rectangle, Then calculate the area of the rectangle,

10 multiplied by 5 =50

Thats the area of rectangle 1

Rectangle 2

3 multiplied by 6 = 18

Triangle

4 times 3 divided by 2 = 6

Thus

6 + 18 + 50  = 74

PLEASE GIVE BRAINLIEST AND 5 STARS.

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
