Question

George has a rectangular wooden deck that measures 2.5 meters by 3.4 meters

Answer 1

Answer: (a) 11.8

               (b) 13

Step-by-step explanation:

Since George wants to put a string of lights around , it means we will have to consider the perimeter of the shape.

Perimeter of a rectangle is given by :

P = 2( L+B)

P = 2 ( 2.5 + 3.4)

P = 2 ( 5.9)

P = 11.8 meters

(b) Since he wants to put an addition to his wooden deck that is 0.6 meters longer , then the perimeter will be the perimeter of the first shape + 2(0.6). We used 2(0.6) because the two lengths of the rectangle must be considered

Therefore, we have

P = 11.8 meters + 2(0.6)

  = 11. 8 + 1.2

= 13 meters

Therefore George needs 13 meters length of light
