Answer:
36 am I wright
because in this case we should always multiply
Is that a question or a true or false question..
Length = 2(width)
perimeter = 36 cm
using variables where x = width and y = length
Perimeter = 2x + 2y = 36 cm
y = 2x
solving for length 2x + 2(2x) = 36 cm
2x + 4x = 36 cm
6x = 36 cm
x = 6 cm
so y = 2(6 cm) = 12 cm
area of rectangle = 12 cm * 6 cm = 72 cm^2
Substitute the variable for value we're given.
-9(2) - 7
-18 - 7 = -25
So, -25 is the answer.
Answer: 36.84
(lmk if this isnt right)
Step-by-step explanation:
To find the perimeter of the rectangle:
3+3+3+3+3+3=18
or
3(6)=18
To find the diameter of the circle:
12-(3+3)
12-6=6
You can combine the 2 half circles to make 1 full circle since they both have the same diameter. Use the circumference formula to solve.
C=πd
Substitute
C=3.14(6)
Multiply
C=18.84
Add the perimeter of the rectangle and the circumference of the circle.
18+18.84=36.84
