1. length = 88 m., 2. width = 75 cm.

Step-by-step explanation:

To find perimeter, we need to add together the measure of all of the sides. Since we now that the garden is a rectangle, we know that two of the sides are the same length and the other 2 sides are the same length.

The equation for finding perimeter in this question: P = w + w + l + l

let's put the values we know into the equation.

318 = 71 + 71 + l + l

Combine like terms: 318 = 142 + 2l

Subtract 142 from both sides to isolate the 2l: 176 = 2l

Divide both sides by 2 to isolate the l: 88 = l

To find area, you use this equation: A = l * w

Let's put the values we know into the equation

6,675 = 89 * w

Divide both sides by 89 to isolate the w

75 = w
