Question

each side of a square field measures 21 metre.adjacent to the square field there is a rectangular field whose sides are in ratio4:3.if the perimeter of both the fields are equal, then find the dimensions of rectangular field.

Answer 1

Perimeter of sq field = 4 (21m)
= 84m

Perimeter of rectangular field = 2 (4x + 3x)
84m = 2 (7x)
84m = 14x
x = 84/14
x = 6m

So, 4x = 4 (6) = 24m
3x = 3 (6) = 18m

To confirm, lets find perimeter of rectangulaf field = 2 (l + b)
= 2 (24m + 18m)
= 2 ( 42m )
= 84m

So, the dimensions are 24m and 18m

Answer 2

Answer:

x + 8x/100 = 769

108x/100 = 769

x = 76900/108

x = 712.03
