The parallel sides of a trapezium field are 12 m and 20 m. If distance between the parallel sides is 8 m, find the area of the field.

The parallel sides of trapezium field are 12 m and 20 m . If distnace between the parallel sides is 8 m, find the area of the field

The perpendicular distance between the two parallel sides is 15m . difference of the parallel sides is 16m find the length of the parallel sides

Find the angle between the lines whose direction cosine are given by the equation: "l"-"m"+"n"=0" and l"^2-"m"^2-"n"^2=0

m equi spaced horizontal lines are intersection by n equi spaced vertical lines. If the distance between two successive horizontal lines is same as that between two successive vertical lines, then find the number of squares formed by lines if (m
