Question

frends plz help me to find the solution​

Answer 1

Answer:

Dimensions of rectangular field is 3 feet and 13 feet.

Step-by-step explanation:

1 ) Let the width of rectangle(b) = x

Length of rectangle is(l) = 4 + 3x

Perimeter of rectangle = 2(l + b)

                                32 = 2(4 + 3x + x)

                                32 = 2(4 + 4x)

                                4 + 4x = 16

                                4x = 16 - 4

                                4x = 12

                                x = 12/4

                                x = 3

Width of rectangle = 3 feet.

Length of rectangle = 4 + 3x

                                  = 4 + 3(3)

                                  = 4 + 9

                                  = 13 feet.

2) CP = Cost Price

SP = Selling price

Given,

SP = 5885 Rs

% Increment = 7%

According to question,

CP + CP × increment% = SP

CP + CP × 7% = 5885

CP + 0.07CP = 5885

1.07CP = 5885

CP = 5885/1.07

= 5500 Rs

So, The original cost  = 5500 Rs
