Help plzzz it’s math

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

On average, how many more hits will he get when he bats 100 times at home during the day as opposed to 100 times away at night?

Can you me find the slope! (30 points)
