Question

the area of a Trapezium is 850 square CM one of the parallel sides is 64 cm and the perpendicular distance between the parallel sides is 17 cm find the length of the parallel side

Answer 1

36 is the right answerr

Answer 2

if area =850
then area=1/2×h×(a+b)
so,
850=1/2×17(64+b)
850=544+8.5b
8.5b=850-544
8.5b=306
b=306/8.5
b=36cm
