Problem 2

Anna is planning to decorate her square garden of length 127 feet. The cost to decorate a foot is 5 dollars. Then how much will it cost to decorate the full garden?

Okay, lets begin

The length of the garden = 127 feet The cost to decorate 1 square foot of the garden = 5 dollars. To find the total cost to decorate, we find the area of the garden, Area of the garden = area of the square = a² Here a = 127 Therefore, the area of the garden = 127² = 127 × 127 = 16,129. The cost to decorate the garden = 16,129 × 5 = 80,645. The total cost = 80,645 dollars

Explanation

To find the cost to decorate the garden, we multiply the area of the garden by the cost to decorate per foot.
