Answer 1

Answer:

. The figure constitute a rectangle

and Rt. triangle

The base of the triangle is 90-30

=6om

hypoten use is 100m

Then the height of the triangle =

v100^2-60^2 =v6400 = 80m

Area of the Rt triangle 1/2bh=

60x80/2=2400 m2. (i)

The dimensions of the rectangle

lengthl=30, and breadth=80

Area of rectangle = lxb=30x80

= 2400. (2)

Total area of the figure=2400+2400

= 4800m2

= 4800x5= Rs24000
