Question

the length of a Rectangular Garden is 5/4 times its breath. the expenditure for four layered wiring around the garden at rupee 36 per metre is rupee 129600 what is the breath of the garden

Answer 1

Answer:

let breadth of 5he garden is x m

then length=5x/4 m

perimeter=2(5x/4+x) m=2(9x/4) m=9x/2 m

again , perimeter of the garden is

129600/36 m

=21600/6 m

=36 m

so, 9x/2=36

=> x=36×2/9=8

breadth of the garden is 8 m
