Question

9.) A field is in the shape of a trapezium whose parallel
sides are 25 m and 10 m. The non-parallel sides
are 14 m and 13 m. Find the area of the field.​

Answer 1

Answer:

So area of trapezium = Area of rectangle + Area of triangle

Use heroins formula find Area of triangle with sides 13, 14, 15,

Step-by-step explanation:

S = 13+14+15/2

= 21

√21*8*7*6 = 7*3*4 = 84 sq.m

Area of triangle with base 15 is given by 1/2*15*height = 84

height = 56/5m

Area of rectangle = 56/5*10 = 112 sq.m

so Area of trapezium = 84 + 112 = 196 sq . m
