    Ok, do you know the formula to find the area of a rectangle?

    the formula my math gives me to find the answer is total area= ph+2B

    Right! Remember that a capital P = permeter of the base, and capital B = area of the base. A = Ph + 2B So lets find the perimeter and area of the base.|dw:1363050666823:dw|

    Remember, the perimeter is the sum of all the sides. For rectangles, there is a simple formula 2* length + 2*width

    So we have: P = 6 B = 10 h = 5 A = Ph + 2B A = 6(5) + 2(10)

    Same steps. A = Ph + 2B So lets find the perimeter and area of the base. |dw:1363053998087:dw|

    Perimeter = 12 * 4 = ? Area = 12 * 12 = ?

    Great! Lateral area is the area of the faces, not including the bases of the figure. The formula for this is: LA = Ph (P = perimeter of the base) |dw:1363054464534:dw|We need to find the missing side length.

    how do i do that? i forget is it 8?

    To do this we use the Pythagorean theorem: \[\large a^2 + b^2 = c^2\]Where a, b, and c are the side lengths. ****c always stands for the hypotenuse(longest side)**** So we have: \[\large 6^2 + 4^2 = c^2\]\[\large 36 + 16 = c^2\]\[\large 52 = c^2\]Find the square root to solve for c.\[\large \sqrt{52} =\sqrt{c^2}\]\[\large 7.211 = c\]

    Perimeter, you're simply adding all the sides. 6 + 7.2 + 4

    write it : \(\large{0 + 16\sqrt{13}}\) or \(\large{0 + 8\sqrt{52}}\)
