Question

Can someone plz help with this?

Answer 1

A = 20 square units ; Type in 20

Explanation:

The simplest way to derive the area of this figure, is to first consider what the shape is itself;

`Criteria of Shape - 2 Bases, 1 pair of Parallel Sides, Composed of two triangles, one square -From this we See that - Shape ; Trapezoid ( neither Right nor Isoceles )`

Knowing that the shape is a Trapezoid, consider the formula ( Average of Bases ) * Height as to solve for it's area;

`Length Of Base 1 - 3 units,\\Length of Base 2 - 7 units,\\Length of Altitude - 4 units,\\`

Now let us substitute these values, solving for the Area;

`Area Of Trapezoid - ( ( Base 1 + Base 2 ) / 2 ) * Height,\\ ( ( Base 1 + Base 2 ) / 2 ) * Height = ( ( 3 + 7 ) / 2 ) * 4,\\( 10 ) / 2 * 4 = 5 * 4 = 20 square units,\\\\Conclusion ; Area of Trapezoid = 20 square units`

Solution; A = 20 square units

Answer 2

A=20 (square units)

Explanation:

B=XW=8-1=7

b=YZ=5-2=3

h=5-1=4

A=(B+b)*h/2

A=(7+3)*4/2=10*2

A=20 square units
