A - area of a trapezoid;
a, b - two bases.
A = h * ( a + b ) / 2 / * 2 ( we have to multiply both sides by 2 )
2 A = h *( a + b )
2 A = h a + h b
h b = 2 A - h a
b = ( 2 A - h a ) / h
b = 2 A/h - a
Answer: D )
Answer:
1184.5
Step-by-step explanation:
150+400+180+300=1030

I hope this helps you :)
20%, I believe. The piece of wood lost 2 ounces of moisture after drying, and 2/10 = 20/100
Answer:
Step-by-step explanation:
The perimeter is basically the outline of the shape. The perimeter of a rectangle is given by P=2l+2w, where l is the length and w is the width. Thus, the perimeter of the flower bed would be given by P=2(3n5o)+2(5n5o).
