Answer:
Step-by-step explanation:
the formula to find the area of rectangle is length X breadth. in the question, the measurements are given like in the first part it is p as length and q as breadth. so we must multiply the two variables.
when we do so pXq, we get pq. As they are both variables so it'll remain the same. but in the second part its 10m and 5n.
10m X 5n, we get 50mn how? BECAUSE 10 and 5 are numbers so we can multiply it directly. however we cant directly multiply variables or unlike terms so it'll remain varaibles only.
hope it helped :)
