Question

a figure is in shale of a trapezium having parallel sides 25m,20m,10m. The non parallel sides are 14m,13m.find the area of the field​

Answer 1

Answer:

196 m^2

Step-by-step explanation:

Draw a line BE parallel to AD and draw a perpendicular BF on CD.

It can be observed that ABED is a parallelogram.

BE = AD = 13 m

ED = AB = 10 m

EC = 25 − ED = 15 m

For ΔBEC,

Semi-perimeter,

By Heron’s formula,

Area of triangle

Area of ΔBEC

m2= 84 m2

Area of ΔBEC

Area of ABED = BF × DE = 11.2 × 10 = 112 m2

Area of the field = 84 + 112 = 196 m2

Answer 2

Answer:

Your question is incorrect since a trapezium cannot have three parallel sides.
