Answer:

= 52sqrt3

Step-by-step explanation:

Area of a trapezium is given by the formula;

1/2(a+b)h

Where a and b are the parallel sides and h is the perpendicular height.

a = 15 ft, b= 11 ft and h = 4√3

Therefore;

Area = 1/2 (15+11) 4√3

        = 1/2 × 26 × 4√3

        = 52√3 ft²

Answer:

Choice b is correct.

Step-by-step explanation:

We have to find the area of trapezoid.

The formula for area of trapezoid is:

A = 1/2 (a+b )h

In the formula a and b are parallel sides and h is perpendicular height.

In the figure, a = 15 ft , b = 11 ft , h = 4√3 ft

Hence,

A = 1/2 (15+11)(4√3)

A = 1/2 (26)(4√3)

A = 52√3 ft² is the area of trapezoid.
