Answer:
- fraction
- denominator
- product
- numerator
Step-by-step explanation:
When you multiply a <u>fraction</u> by a whole number, the denominator in the product is the same as the <u>denominator</u> of the fraction. The numerator in the product is the <u>product</u> of the whole number and the <u>numerator</u> of the fraction.

That's the rule. It is derived from the fact that multiplication indicates repeated addition.
To solve this question, you have to take the 2D shape and divide it up into 6 boxes, of which you find the area of each. For easier reference, here's a picture where I've numbered the boxes.
Box 1: Nothing special here, just 25*12= 300 cm²
Box 2: The height of box 2 is obvious but the length is found from the above box. 25*18= 450 cm²
Box 3: Box 3 is the opposite of box 2, with an obvious length, but a width which is found from box 2. 12*18= 216 cm²
Box 4: Box 4 receives its height from box 2 and its length from box 6. 25*18= 450 cm²
Box 5: Box 5 has an obvious length but receives its height yet again from box 2. 12*18= 216 cm²
Box 6: Box 6's parameters are both obvious. 25*12= 300 cm²
The next step is to add the area of all the sections. 300+450+216+450+216+300= 1932 cm²
I hope this helped you!
