Step-by-step explanation:
Answer:
426 cm^2
Step-by-step explanation:
Let, the area of the given figure be A
Let's imagine that the rectangle (at the bottom right) is present.
Then, A = Area of trapezium - Area of rectangle
= { 1/2 * ( 18 + (20+4) ) * ( 13+9 ) } - ( 4 * 9 )
= 462 - 36
= 426
[If there's any mistake, please inform me]
It is false. Since you don't know what is the variable equal to. But multiplication can't be in associative property.
The radius is half of the diameter.
To find the circumference, use the equation C=2(pi)r or C=(pi)d.
r meaning radius. d meaning diameter.
(pi) is about 3.14 or 22/7
