Question

Monica is building a 4ft sidewalk around her flower garden. Find the are of the sidewalk.

Answer 1

Answer:

Option D, 336

Step-by-step explanation:

The first step is to find the area of the flowerbed. 25*9=225 feet squared. The next step is to pretend that the sidewalk takes up the full space, and then subtract the area of the flower garden within to find the area of the sidewalk. Since the sidewalk is 4 feet wide, it makes the dimensions of the sidewalk added to the garden 8 feet wider on all sides. This means that the total area of the two is (25+8)*(9+8)=33*17=561 squared feet. Now, all you need to do is to subtract the area of the flower garden. 561-225=336 feet squared, or option D. Hope this helps!

Answer 2

Answer:

(20x30)= 600

that's the area of rectangular plot

3ft wide sidewalk means both +3 on left and +3 on right, also both +3 up and +3 down

which means u have to do 26x36=936

then subtract 

936-600=336 square feet
