Explanation:
__________________________________________________
Area of trapezoid: A = (1/2) (base 1 + base 2) h ;
or; write as: A = (1/2) (b₁ + b₂) h ;
in which: A = area of trapezoid;
b₁ = length of one of the bases;
b₂ = length of the "other" base (not already used for "b₁") ;
h = height;
Given: h = 6 ft. ;
b₁ = 7 ft. ;
b₂ = 5 ft. ;
_______________________________________
Find the area of the trapezoid:
______________________________
A = 1/2 (7 ft + 5 ft) 6 ft. ;
A = 1/2 (12 ft) * 6 ft. ;
A = 36 ft² ; which is answer choice: [B].
