Question

select the correct answer. a rectangular - shaped park contains two gardens of multi - colored roses. sidewalks enclose the whole park and each of the gardens. what is the total length of the sidewalks that surround these two gardens? a. 144 meters b. 148 meters c. 94 meters d. 134 meters

Explanation:

Step1: Analyze the lengths of the sides of the rectangles and the paths

We need to find the total length of the sidewalks. By observing the figure, we can calculate the sum of the lengths of all the sides that make up the sidewalks. There are two long - side lengths and two short - side lengths for the outer rectangle formed by the sidewalks.

Step2: Calculate the sum of the lengths

The lengths of the long - sides are \(30 + 20+20 = 70\) meters each, and the lengths of the short - sides are \(24 + 20=44\) meters each.
The total length of the sidewalks \(L=2\times70 + 2\times44\).
First, \(2\times70 = 140\) and \(2\times44 = 88\).
Then \(L=140 + 88=148\) meters.

Answer:

B. 148 meters
