a. To acquire the area of those two bulletin boards, use the formula for the area of rectangle for each bulletin board which is: Area = l x w. The area of the small bulletin board will be:
Area: 3 x 2
= 6 m²
The area for the bigger bulletin board will be:
Area: 6 x 4
= 24 m²
24 m² - 6 m² = 18 m² - This is the difference of their area.
b. First, double the length and width of the bigger bulletin board by multiplying them into 2: 4 x 2 = 8 m and 6 x 2 = 12 m. The area will be:
Area: 12 x 8
= 96 m²-This will be the area if the size of bigger bulletin board is doubled.
