Question
Steven calculated the area of a square to be square yard. What is the side length of the square?
Hint:
calculate the square root of 1/81
The correct answer is:
Given, area of square = 1/81 sq yard. This means that the square of side length is 1/ 81. This means that we need to find the square root of 1/ 81. Square root of 1 is 1. To find the square root of 81, let’s find the factors of 81. By using hit and trial method, we can write that 81 = 3 x 3 x 3 x3 = 9 x 9. Hence, 9 is the square root of 81. Hence, our required answer is 1/9 , which is the square root of 1/81.

Irene buys a talking doll for $11.66 and batteries for $3.22. She pays with a $30 bill. Estimate how much change she should get ?
Cost of doll=$ 11.66
Cost of batteries =$ 3.22
Total cost = 11.66 + 3.22 =$ 14.88
Amount paid = $ 30
Amount to be returned = $ 30- total cost= $30 - $ 14.88= $ 15.12$
