The formula for area of a trapezoid is: 1/2 (b1+b2) h
b1=10
b2=10·2=20 because it stated the side parallel is twice as long as the side above
h=10/2=5 because the height is half as long as the give side length
area of the trapezoid is: 1/2 (10+20) 5
(5·10)·5
50·5
area of the trapezoid is 250 in²
It would be the second one if you follow PEMDAS
2.6 and 2.4. they are the decimals next to 2.5
Answer:
8
Step-by-step explanation:
3 - -5 = 8
filling space here dont mind this
<u>Final Answer:</u>
x = 20
<u>Step-by-step explanation:</u>
we'll be using the pythagorean theorem method, in this triangle the missing letter is a.
formula: 
a = x
b = 21
c = 29
a = 
a =
(note: 29² = 29 × 29 = 841 and 21² = 21 × 21 = 441)
a = 
a = 20
x = 20
