Finding the Length and Area

To find the length and area based on the given width and perimeter, we can use the following formulas and calculations:

1. Finding the Length (L): - The perimeter (P) of a rectangle is given by the formula: P = 2(L + W). - Given: P = 36 cm, W = 8 cm. - Using the formula, we can solve for L: - 36 = 2(L + 8) - L + 8 = 36 / 2 - L + 8 = 18 - L = 18 - 8 - L = 10 cm

2. Finding the Area (A): - The area (A) of a rectangle is given by the formula: A = L * W. - Given: L = 10 cm, W = 8 cm. - Using the formula, we can calculate the area: - A = 10 * 8 - A = 80 cm^2

Therefore, the length of the rectangle is 10 cm and the area is 80 cm^2.
