Can someone me identify the bases and the height of this trapezoid on problem 1? you!

1. (The base on top is 15 ft.  
To find the base on the bottom you have to first find the length of the right side of the triangle. 7 - 4 = 3. Then, square both sides of the triangle and add them together. 15^2 + 3^2 = 234  
Next take 234 and find its square root = 15.3. The bases of the trapezoid are 15 and 15.3)  
2. (Both bases and the height.)  
3. (2l + 2w does not belong, all of the equations are formulas for area but that one is perimeter)

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
