Math: The relationship Between Circumference and Area. Quick check
Find the area of the figure below.
7 in, 6 in and 12 in= (A = 1/2 (b1 + b2) (h)
1. 114 in2
2. 57 in2
3. 25 in2
4. 12.5 in2
To find the area of a trapezoid, we use the formula A = 1/2 (b1 + b2)h, where b1 and b2 are the lengths of the two parallel bases and h is the height.
In this case, the lengths of the two parallel bases are 7 in and 12 in, and the height is 6 in.
A = 1/2 (7 + 12) 6
A = 1/2 (19) 6
A = 1/2 * 114
A = 57 in2
Therefore, the area of the figure is 57 in2.
The correct answer is 2. 57 in2.
