what's the area of the shape .

Answer:
[tex]Area = 210m^2[/tex]
Step-by-step explanation:
The attached shape is a trapezium and the given dimensions are:
[tex]B_1 = 10m[/tex] -- Base 1
[tex]B_2 = 20m[/tex] --- Base 2
[tex]H = 14m[/tex] --- Height
Required
Calculate the area
The area is calculated as thus:
[tex]Area = \frac{1}{2}(B_1 + B_2) * H[/tex]
[tex]Area = \frac{1}{2}(10m + 20m) * 14m[/tex]
[tex]Area = \frac{1}{2}(30m) * 14m[/tex]
[tex]Area = 15m * 14m[/tex]
[tex]Area = 210m^2[/tex]
