Answer:
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
