Question

need help with this. Hope someone can help

Answer 1

Since the length and width of the pictures are given in cm, let's convert all lengths to cm.

Remember that 1 m = 100 cm

3.6 m = 360 cm

1.8 m = 180 cm

The area of a rectangle is A = LW. The area of the board is

A = LW = 360 cm * 180 cm = 64,800 cm^2

The area of each picture is 6 cm * 6 cm = 36 cm^2

To see how many pictures fit in the board, we divide the area of the board by the area of one picture.

(64,800 cm^2)/(36 cm^2) = 1,800

Answer: 1,800 pictures

Answer 2

Area of the board = 3.6 * 1.8 = 6.48 m^2 = 6.48 * 100 * 100

= 648 * 10,000 = 64,800 cm^2

Area of 1 photo = 36 cm^2

So number of pictures which will fit on the screen

= 64,800 / 36

= 1,800 answer
