Answer:
The kitchen requires 288 sq. ft. of tile
The master bathroom requires 180 sq. ft. of tile
In total, we will spend $1170
Step-by-step explanation:
The area of the kitchen is length * width:
Area of Kitchen =
sq. ft.
The area of the master bathroom is length * width:
Area of Master Bathroom =
sq. ft.
- <u>Question 1: "How many square feet of tile do I need for the kitchen?"</u>
The kitchen requires 288 sq. ft. of tile
- <u>Question 2: " How many square feet of tile will I need for the bathroom?"</u>
The master bathroom requires 180 sq. ft. of tile
- <u>Question 3: "If the tile costs $2.50 per sq ft, how much money will I spend on tile?"</u>
In total, <u><em>we require
sq. ft. of tiles</em></u>. If $2.50 is charged per square feet, in total we will spend:
dollars
First step: partition the number you want to square root into a block of 2 digits, starting from the last digit (first diagram)
Second step: As our number is a five-digits, we ends up with 2 28 01. Pick a number that could be squared to get the first partition, 2. This number is 1, since 1×1=1
Third step: Write 1 on the top and on the side, as shown in the second graph
Fourth step: Double the number on the side, which is 1+1=2 and use this number as the first digit for the next multiplier. Meanwhile, subtract 1 from 2 inside the root sign to get 1, then pull the other two digits, 28
Fifth step: We need a value in the boxes that when we multiply together will give a number less than 128. We choose 5 as 25×5=125
Sixth step: Subtract 125 from 128 to give 3, and as the same concept with long division, bring down the 0 and the 1. So we have 301
Seventh step: Add 5 to the multiplier on the left, so 20+5=30, which we will use on the side as the hundred and ten digits.
Final step: Find a number to fit in the boxes. We choose 1 since 301×1=301
And hence the square root of 228801 is 151
It is the way a function is written.
