Rob cuts grass as a job. a neighbour asked rob to give a quote for his backyard. rob noticed that the yard was a rectangle shape. he used the formula = × to calculate the area (in square metres). he measured the length along the fence (l=16.2 m) and the length next to the house (b= 6.7m). show working
a) using a calculator and the formula, find the area of the yard.

b) round your answer to the nearest whole number.

c) rob charges $0.46 per square metre. what is the quote for the neighbour’s backyard?
d) if rob didn’t have a calculator and simply rounded off the lengths to the nearest whole number, what would this area be? what would be the implications of using this approximation for the quote?

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
