Question

15. The length of rectangular Mathematics Garden is 5 m longer than its width. The are of the garden is 84 square meters. Find the width of the garden.

Answer 1

Answer:

let width be x

length will be 5x

A. of garden = 84 m.sq.

A. of garden = l × b

84m.sq. = x x 5 x

84 = 5 X x X

84/5=x2

√84/5= X

Width =√84/5m

Answer 2

Answer:

ans let width is x m

then length = x+5 m

area= 84 m

area =l x b

x * x +5 = 84

x^2 =84 -5

x ^2 = 79

x = \sqrt{79}

x= 8.8 m
