Explanation Given Information: One roofing square is equals to 100 square feet and 100 square feet is equals to 10 feet multiplied by 10 feet. Formula used: Steps to multiply a number end in zero. Step 1: Do calculation in your mind by eliminating zeros from the end of each number. Step 2: Multiply with the new number and attach the total number of zero at the end of the product which eliminated in previous step. Steps to divide numbers ending in zero: Step 1: Do calculation in your mind by eliminating the same number of ending zeros form both the divisor and dividend. Step 2: Divide the new number. Calculation: Consider the provided information, Roof measured is 45 feet × 20 feet Multiply both the numbers as shown below
