(x - 8)^2 = 144
take the sq rt of both sides
x - 8 = 12
x = 12 + 8
x = 20
20 feet by 20 feet
Perimeter of a rectangle can be represented by 2* length + 2 * width
We can represent the width with the variable x
We can represent the length by the expression 3x-1
So, now we can make a forumla and solve
2(3x-1) + 2(x) = 30
6x-2+2x = 30
8x = 32
x = 4 is the width of the rectange.
Now we find the length
3(4)-1
11 = Length
Answer:
38 cm
Step-by-step explanation:
Circumference is given by
C = pi *d
C = pi *12
C = 3.14 * 12
C=37.68
Rounding to the nearest cm
C = 38
27 multiplied by 10 will give you the answer. 27 x 10 = 270.
