Find the area of the figure if needed round to the nearest tenth isosceles trapezoid

The image of the isosceles trapezoid is missing, so i have attached it.

A = 18 Sq.ft

Step-by-step explanation:

From the image attached, it is a trapezium.

Formula for area of a trapezium is;

A = ½(a + b)h

Where;

a and b are the parallel sides

h is height.

From the image attached;

a = 4ft

b = 8 ft

h = 3 ft

Thus;

A = ½(4 + 8)×3

A = ½ × 12 × 3

A = 18 Sq.ft
