    look at the diagram... see how it shows one of the bottom sides as 8? And the top shows the other two sides as 7 and 5 Perimeter = 8 + 7 + 5

    Adding is good. Reading the diagram and realizing that all you need to do for perimeter is add those 3 sides is even better. For # 3, P = 20 is correct.

    B is the area of the base. The formula for area of a triangle is, as you surely know, 1/2 * base * height Again, the base side has length 8. And the height is shown as 4.3. (I'm just reading the diagram... no magic) So find 1/2 * 8 * 4.3

    Ok, great. Next is lateral surface area. Check that diagram again... the side surfaces are all rectangles, right? And area of a rectangle is length X width, or length X height (basically one side X the other side). So, please tell me the the length and height, then multiply to get the area of each of the 3 lateral side surfaces: Lateral side 1: Length: Height: Length X Height = ? Lateral side 2: Length: Height: Length X Height = ? Lateral side 3: Length: Height: Length X Height = ? This is really easy... it's just reading the length of each edge, and all the heights are the same... then it's easy multiplying... you know how to do this.

    This is like a puzzle... you find the bottom area... and the bottom area is the same as the top area. Then, you find the side areas... then you add the bottom, top, and all 3 sides together. You found the bottom area earlier... 17.2. So that's also the top area... Now you have to find the sum of all the side areas... All sides are rectangles with area = length X height So the first is : length1 * height And the 2nd is : length2 * height And the 3rd is : length3 * height And the sum of all three areas is: length1 * height + length2 * height + length3 * height But since height is the same, you can think of "distributive property" and rewrite the lateral side areas as: height * (length 1 + length2 + length3) And notice that adding those 3 lengths together is the same as the perimeter, and you already found that to be 20. So the lateral side area is height * perimeter = height * 20

    So put in the value of the height (height = 9), and solve for lateral side area... that's the 3rd part. Then, for total surface area, add the lateral side area you just now found to the top area + the bottom area... remember, those were each 17.2 So the total surface area = (9 * height) + 17.2 + 17.2

    3rd part: lateral side area = 180 4th part: total area = 180 + top + bottom = 180 + 17.2 + 17.2 = 180 + 34.4 = 214.4
