Mr. Go plans to fence his rectangular garden. If the garden measures 19m. by 15m., how much will he need if a decimeter of fencing material costs P11.15?

Sagot :

First, we need to know the perimeter of the garden.
P = 2l + 2w
P = 2 (19 m) + 2 (15 m)
P = 38 m + 30 m
P = 68 m

Then convert 68 m to dm
1 m = 10 dm
68 m = 680 dm

then...
[tex] \frac{680 dm}{P 11.15/dm} = P60.99[/tex]

Therefore, the answer to your question is P60.99
Step 1: Find the perimeter of the fence:
Perimeter of rectangle = 2 (L) + 2 (W)
Perimeter = 2 (19 m) + 2 (15 m)
                 = 38 m + 30 m
                 = 68 m

Step 2: Convert meter to decimeter
1 meter = 10 decimeters
68 m x 10 dm/m = 680 m
Perimeter = 680 dm

Step 3:  Multiply the fencing material cost per decimeter by the perimeter of the fence:

680 dm × Php 11.15 / dm = Php 7,852

ANSWER:  Mr. Go needs Php 7,872 for the fencing materials.
