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
The answer is 15/100 x 45 =6.75 minutes <span />
