Answer:
56.8 m²
Step-by-step explanation:
This shape is clearly a trapezium / trapezoid. So :
Area of a trapezium is given by the formula :
[tex]\frac{a+b}{2} h[/tex]
Substitute values given in diagram :
a = 4.2
b = 10
h = 8
[tex](\frac{4.2+10}{2} )8[/tex]
7.1 × 8 = 56.8
Units will be m² as this is area
Giving us our final answer of 56.8 m²
