Answer:
# 4 (-5,2) should be placed one more place to the right
#5 (5,1) should be moved once up
Step-by-step explanation:
:)
Just move the decimal twice to the right. So 11%
Because when you multiply by 10, it adds a zero to the end of the number, like 12*10 = 120, so vise versa for dividing

Answer:
24 cm²
Step-by-step explanation:
To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...
P = 2(AB +BC)
BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm
Then CD is ...
CD = BD -BC = 9 cm -4 cm = 5 cm
The area of the trapezium is given by the formula ...
A = (1/2)(b1 +b2)h
A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²
The area of trapezium CDEF is 24 cm².
