Answer:
perimeter is 35.6 area is 108
Step-by-step explanation:
it helps to draw a picture. first the perimeter of the rectangle is 4x2 +12=20 we wont be needing one of the twelves because it is connected to the triangle the area or the rectangle is 12x4=48. now for the triangle. we will need the Pythagorean theorem to find the sides first split the base in half 12/2=6 now we use the height and the base 6^{2} +5x^{2} =6
2
+5x
2
= 61 the square root of 61 is about 7.8 the perimeter is 7.8+7.8 +12 but we wont need the base because it is attached to the rectangle =15.6 the area of the triangle is like half a square Base times height though 12x5=60
the whole perimeter if 15.6+20=35.6 the area is 60+48=108

Answer:
18
Step-by-step explanation:
The diagonals of a parallelogram <em>bisect</em> each other, which is to say they split each other in half, and since each half length is equal to the other, we can say that
3x + 3 = 6x - 57
Which, after some algebraic manipulation, gives us the solution
x = 18.
Answer:
755 gram lighter
Step-by-step explanation:
Convert 1.1kg into gram by multiplying it with 1000
