Question

the length and the breadth of a rectangular field are in the ratio of 4:3 if the area of the field is 8112 m square find the cost of fencing the failed with firewire 5 time at the rate of rupees 2.85 per meter

Answer 1

Answer:5016

Step-by-step explanation:length and breath: 4x and 3x

Area=length × breadth

4x×3x=8112

12x^2=8112

x=26

Perimeter=(104+78)2

=364

So,

364×5×2.85=5187

Answer 2

Answer:

₹ 105963

Step-by-step explanation:

length = 4x

breadth = 3x

area = L*B

        = 4x*3x = 8112 m square

        = 12x square = 8112 m square

        = 12x = 8112

        = x = 8112/12

        = 676

length = 4*676 = 2704

breadth = 3*676 = 2028

perimeter = 2(L+B)

                 = 2*(2028+2704)

                  = 7436 m

total money required = 7436*5*2.85

                                    = 37180*2.85

                                    = ₹ 105963
