A trapezoid has an area of 5 1/4 ft. sq. If the trapezoid has a base that measures 2 3/5 ft. and a height of 1 1/2 ft., what is the length of the other base?
A) 1 1/10ft. B) 3 1/2 ft. C) 4 2/5 ft. D) 5 7/10 ft
5 1/4=21/4 2 3/5=13/5 1 1/2=3/2 A=1/2(b1+b2)×h 21/4=1/2(13/5+b2)×3/2 21/2=(13/5+b2)×3/2 7=13/5+b2 b2=4.4 or 4 2/5 ft. As a result, C is the correct answer. Hope it help!
