Answer Key : (a) -

Interchanging the distances to C and D, the field may be drawn in th adjoining figure.

We have AB = 40, AF = 30, AG = 20, AH = 10, CH = 30, DG = 20, EF = 30.

 

Area of the field = ar (AHC) + ar(rect. CEFH) + ar (BEF) + ar (BGD) + ar ( AGD)

 

=

 

= 1300 m2.



Next Question :

The measurements of a filed are as shown.

If the total area of the field is 27500 sq. m, then the value of x is equal to  

(a)

25 m

(b)

30 m

(c)

50 m

(d)

75 m
