Step-by-step explanation:
Given that the formula of area of trapezium is :

In the formula, a and b represents the length of trapezium and h is the height. So you have to substitute the following expressions into the formula :





Answer:

Step-by-step explanation:

Answer:
2x-10
Step-by-step explanation:
2(x) - 2(5) = 2x - 10
Answer:
11 and 16
Step-by-step explanation:
A good way to solve these is to work backwards.
X= larger and Y= smaller
if X is 5 more than 2Y than subtract 5 from the total
38 - 5 = 33
divide by 3
33/3 = 11
11 = Y and double that is 22 so add the five back into X and you get 16
