Asurvey plat depicted to the right shows two lots that form a trapezoid. the measures of the parallel sides are 50.29 ft and 91.61 ft. the height of the trapezoid is 51.83 ft. find the combined area of the two lots.

3677.3385ft²

Step-by-step explanation:

The area of a trapezium=1/2(b+l)×Height

where;

b and l are parallel sides

b=the length of one parallel side, the shorter one=50.29 ft

l=the length of the other parallel side, the longer one=91.62 ft

h=is the perpendicular height to b

Replacing;

Area=1/2(50.29+91.61)×51.83=3677.3385ft²

The combined area of the two lots is

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

where

b_1 and b_2 are the parallel sides

h is the height of trapezoid

In this problem we have

substitute in the formula
