Question

A field is in the shape of trapezium whose parallel sides are 25m and 10m the non parallel sides are 14m and 13m find the area of the field

Answer 1

so area of trapezium=1/2(a+b)xh

                                   =1/2(25+10)x14 or 13(due to question not specified)

                                   =17.5 x 14 or 13

                                   = 245(x 14) or 227.5(x 13)

Answer 2

Answer:

Draw a line BE parallel to AD and draw a perpendicular BF on CDit can be observe that ABED is a parallelogramBE=AD=13mED=AB=10mEC=25-ED=15mfor ΔBECsemi perimeter S=13+14+15/2m42/2=21By heron formulaArea of Δ √s(s-a) (s-b) (s-c)Area of ΔABEC= √21 (21-13)(21-14)(21-15)m²[√21(8)(7)(6)]m²=84m²Area of Δ BEC =½x CE x BF=84=12x15xBFBF=16815=11.2mArea of the field = 84+112=196m2Step-by-step explanation:
