Find the area of the following parallelograms: (a)                                             (b)             (c)                                              (d) (e)

Answer:

                (a) Area of the parallelogram \[\text{= base}\times \text{height }\]\[\text{= 7  }\!\!\times\!\!\text{  4 = 28 c}{{\text{m}}^{\text{2}}}\]                 (b) Area of the parallelogram \[\text{= base}\times \text{height }\]\[\text{= 5  }\!\!\times\!\!\text{  3 = 15 c}{{\text{m}}^{\text{2}}}\]                 (c) Area of the parallelogram \[\text{= base}\times \text{height }\]\[=2.5\times 3.5=8.\text{75 c}{{\text{m}}^{\text{2}}}\]                 (d) Area of the parallelogram \[\text{= base}\times \text{height }\]\[\text{=5  }\!\!\times\!\!\text{  4}\text{.8 = 24 c}{{\text{m}}^{\text{2}}}\]                 (e) Area of the parallelogram\[\text{= base}\times \text{height }\]\[\text{= 2  }\!\!\times\!\!\text{  4}\text{.4 = 8}\text{.8 c}{{\text{m}}^{\text{2}}}\]
