Final Answer:
Loretta will need to use trim for 28 feet around the edge of the patio.
Step-by-step explanation:
To find the total length of trim needed, add up the lengths of all four sides of the trapezoid patio. Given the sketch isn't available, let's denote the lengths as follows: the longer parallel sides as a and b, and the shorter non-parallel sides as c and d. The formula for the perimeter of a trapezoid is P = a + b + c + d. Once these measurements are provided, sum them up to find the total trim required.
For instance, if a = 8 feet, b = 12 feet, c = 6 feet, and d = 4 feet, the total trim needed would be P = 8 + 12 + 6 + 4 = 30 feet. However, ensure the measurements match the trapezoid in the sketch to accurately calculate the perimeter.
It's essential to measure each side carefully to determine the precise amount of trim required for Loretta's patio. By adding the lengths of all the edges together, Loretta can ascertain the total footage of trim needed for the wood planks around the patio's edge.
Understanding the shape and measurements of the patio is crucial for an accurate determination of the trim required. Once the lengths of all sides are obtained, summing them will give the total footage needed for the trim, ensuring Loretta has enough wood planks to cover the perimeter.
