Question

find the area of a triangle with (1)base =1680 cm ;height=75 cm (2) base =42 cm ;height =25cm

Answer 1

area of triangle= h * b * 1/2
so area of first triangle = 1680 * 75 * 1/2
                                     = 63000 cm2
area of other triangle = 42 * 25 *1/2
                                    = 525 cm2

Answer 2

to find the area of triangle formula is= h * b * 1/2
so area of first triangle =h * b * 1/2
                                     = 1680 * 75 * 1/2
                                     = 63000 cm2
area of other triangle     =h * b * 1/2
                                     = 42 * 25 *1/2
                                    = 525 cm2
