u have to do distributive property and try to fit the formula of the trapezoid in the expression da
To add and subtract algebraic expressions the simple rule of like terms applies. In your homework that asks for the expression represents the perimeter in units of this trapezoid you will need to find the like terms and simplify.
Area = 1/2*(sum of parallel sides)*perpendicular height
The area is measured in square units.
what trapezoid
40
In the formula for the area of a trapezoid, ( A = \frac{1}{2} (b_1 + b_2) h ), ( b_2 ) represents the length of one of the two parallel sides (bases) of the trapezoid. The other base is denoted as ( b_1 ). The height ( h ) is the perpendicular distance between these two bases. The area is calculated by averaging the lengths of the bases and then multiplying by the height.

Area of a trapezoid: 0.5*(sum of its parallel sides)*height
Area of a trapezoid = 0.5*(sum of parallel side)*height
