Area of a trapezoid is height times the average of the bases,
A= 1/2 h (a + b)
Here we have height h=12 and bases a=30, b=12 so area
A = (1/2) (12) (30 + 12) = 6(42)= 252
Answer: B
Answer:
y=1 (sorry i dont know what justify means lol, i forgot) i know how to solve the answer lol.
Step-by-step explanation:
10y-15-4y=8-2y-15
10y-4y+2y=8-15+15
8y=8
y=1
Answer:
40
Step-by-step explanation:
area= length times width
1 times 10= 10 times 2= 20
2 times 10=20
20+20=40
I think it’s b because x when it’s alone is one i think
