Best ResponseYou've already chosen the best response.3Exactly. Polygon B is a triangle. To find its area we will use the formula for the area of a triangle.

Best ResponseYou've already chosen the best response.3Now we need to find out about polygon A. You can see it has 4 sides. Each set of two opposite sides has the same length. Do you know what polygon A is?

Best ResponseYou've already chosen the best response.3It is close to a rhombus in certain way, but a rhombus has all sides of equal length. Polygon A is a parallelogram.

Best ResponseYou've already chosen the best response.3Now we need to find the formulas for the area of a parallelogram and the area of a triangle.

Best ResponseYou've already chosen the best response.3\(\large A_{parallelogram} = bh\) \(\large A_{triangle} = \dfrac{bh}{2} \)

Best ResponseYou've already chosen the best response.3The area of a parallelogram is the base times the height. The base can be any side of the parallelogram. Once you choose a side as the base, then the height is a segment that goes from that base to the opposite side and is perpendicular to both sides.

Best ResponseYou've already chosen the best response.3In your figure, we see that we can choose the side of 24yd length to be the base. Then the height is the 12yd dashed segment. Since we have a base and a height, we can find the area of the parallelogram.

Best ResponseYou've already chosen the best response.0so 12 * 24 which equals 288 , correct?

mathstudent55

Best ResponseYou've already chosen the best response.3Yes, for the parallelogram. Now we look at the triangle below.

Best ResponseYou've already chosen the best response.0ok I was thinking to do 15 * 8.4 which equals 126 , do we do that or what other should we do

Best ResponseYou've already chosen the best response.3We need a base and a height for the formula. Any side of a triangle can be a base. Then the height is the length of a segment that is perpendicular to the base and ends in the opposite vertex.

Best ResponseYou've already chosen the best response.0ok I got the answer already!

mathstudent55

Best ResponseYou've already chosen the best response.3Now that we see we can use the side of length 24 yd to be that base and the 8.4yd side as the height, we use the formula for the area of a triangle. \(\large A = \dfrac{bh}{2} \) We multiply together the base and the height and we divide by 2.

Best ResponseYou've already chosen the best response.315 yd is not a dimension of the triangle. It is the side of the parallelogram.

Best ResponseYou've already chosen the best response.0math is that correct because thats what i got too

Best ResponseYou've already chosen the best response.3Total area = area of parallelogram + area of triangle = \(bh + \dfrac{bh}{2} = 24 \times 12 + \dfrac{24 \times 8.4}{2} \) \(= 288 + 100.8 = 388.8 ~yd^2\)

Best ResponseYou've already chosen the best response.3The final answer is that the area of the figure is 388.8 square yards.

Best ResponseYou've already chosen the best response.3@Bella111 Be careful with the area of the triangle. Use base 24 yd and height 8.4 yd. Multiply the base by the height and divide by 2. Area of triangle = (24 yd * 8.4 yd)/2 = 100.8 yd^2

mathstudent55

Best ResponseYou've already chosen the best response.3Then when you add the area of the triangle, 100.8, to the area of the parallelogram, 288, you get the total area of 388.8 sq yd.
