Question

The adjacent sideof a parallelogram 36cm and 27cm and lenght if the perpendicular distance between the shorter side is 12 cm find the distance between the longer side

Answer 1

$ar = \binom{1}{2} bh \\ = 0.5 \times 27 \times 12 \\ = 162 \\ 162 = \binom{1}{2} bh \\ 162 = 0.5 \times 36 \times h \\ 162 \div 18 = h \\ 9 = h$
