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