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

10x

step-by-step explanation:

the greatest common factor 30 and 20 is 10

5 is a common factor of 30 and 20 but 10 is also a factor and 10 is greater than 5 so 5 will definitely not be apart of our answer

now the most amount of x's you factor our is just 1 factor of 1

so 10x the gcf of the terms in the polynomial
