Perimeter of the garden=120+80+50 =250m As space of 3 m wide for a gate is left on one side, so the length of wire required=(250-3)=247m. Cost of fencing=247X20=Rs 4940. semiperimeter(s)=perimeter/2 =250/2=>125m Area of triangle is given by A= sqrt(s(s-a)(s-b)(s-c))=sqrt(125x5x45x75)=(25x15sqrt(15))...

Perimeter = 120+80+50 = 250 m Leaving 3 m for the gate, the length to be fenced = 247 m Cost of fencing = 247 x 20 = Rs 4940 Area of the park = 1/2 x base x Altitude = 0.5 x 80 x 50 = 2000 sq m

Area of a triangle =s (s-a)(s-b)(s-c); where s=(120+80+50)÷2=125 Area to plant grass= 125×5×45×75=21,09,375sq.m. Length of barbed wire=perimeter of the field-space for door =120+80+50-3=247m Cost of fencing=247×20= Rs.4940

using Henon's(s-a)(s-b)(s-c)=?125×5×45×75=(25×15)?15=375?15sq.m Cost of fence without gate=(250-3)×20=247×20=RS.4940

Length of garden (perimeter)=120+80+50=250 Now s=(a+b+c)/2=125 Area=?s(s-a)(s-b)(s-c)=?125×5×45×75=(25×15)?15=375?15sq.mt Cost of fence without gate=(250-3)×20=247×20=RS.4940/-
