Question

1. Half the perimeter of rectangular garden ,whose lenght is 4 m more than its width ,is 36 m .find the dimension of garden 2 .given the linear equation 2x+3y-8=0,write another linear equation in two variables that the geometric Al repsentation of the pair so formed is: (1) intersecting lines. (2) parallel lines. (3) coincident lines

Answer 1

according to the ques.
length =?
breadth = L +4

sol. p =2×(l+b)
36=2× (l+l+4) {B=L+4}
36/2=2L+4
18=2L+4
18-4=2L
14=2L
14/2=L
7=L

so b= L+4
b = 7 +4
b=11
