Answer: 20
Step-by-step explanation: the equation would be 15 / 3/4, or 15/1 / 3/4 (the / meaning divide). You would divide it by multiplying the reciprocal of 3/4 (4/3) and 15(/1) , which you would get 20.
Answer:
60cm^2
Step-by-step explanation:
The formula for the area of a trapezium is : 
To work out the area of the trapezium you would first have to add the lengths at the top and bottom (a and b) which is 9+15, this gives you 24cm.
The next step is to divide the value of 24 by 2, this gives you 12cm.
The final step is to multiply the value of 12cm by the height of 5, this gives you 60cm^2. This is because if you were to substitute the values into the formula you would get the same answer.
1) Add 9 and 15.

2) Divide 24 by 2.

3) Multiply 12 and 5.
