Answer:
300 square inches
Step-by-step explanation:
Area of a Trapezoid = 1/2 (b1 + b2 ) × h
h = height 20 inches
b1 = First base = ?
b2 = Second base = ?
From the Question
b1 + b2 = 30 Inches
Hence,
Area of the Trapezoid = 1/2 (30) × 20
= 1/2 × 30 inches × 20 inches
= 300 square inches
The Area of the Trapezoid = 300 Square inches

Answer:
(2x +y)(2x -y +6)
Step-by-step explanation:
The shaded area is the difference of the areas of the outer square and the inner square. In turn, those areas are the square of the edge dimension of the square. So, the shaded area is the difference of squares:
area = (2x +3)² -(y -3)²
The difference of squares is a "special product" in that it has a factored form that is worth remembering.
a² -b² = (a -b)(a +b)
Using this form for our area, we have ...
area = ((2x +3) -(y -3))((2x +3) +(y -3))
area = (2x -y +6)(2x +y)
