Zorluk: KolayRectangular Area Applications

A contractor is preparing to apply sealant to a new rectangular patio that measures 1414 yards in length and 55 yards in width. If the sealant costs 33 dollars per square yard, what is the total cost, in dollars, to seal the entire patio?

Cevap: 210 dollars

Cevap

210
To find the total cost, you must first determine the area of the patio by multiplying the length (1414 yards) by the width (55 yards), which equals 7070 square yards. Then, multiply this area by the cost per square yard (33 dollars) to get the total cost of 210210 dollars.

Adım Adım Çözüm

1
Calculate the area of the rectangular patio.
Area = 14×5=7014 \times 5 = 70 square yards
The cost of the sealant is based on the surface area of the patio.
2
Calculate the total cost to seal the patio.
Total cost = 70×3=21070 \times 3 = 210 dollars
Multiplying the total square yards by the price per square yard gives the final cost.
