A garden has a length of (x + 2) feet and a width of (2x - 1) feet. The garden’s total area is 88 square feet. Find the length.
2 answers:
Answer:
Length=x+2
Width=2x-1
Area of garden =length×width
88sq.ft=2x-1 × x+2
88sq ft=2x^2+3x-2
2x^2+3x-2=88
2x^2+3x-2-88=0
2x^2+3x-90=0
2x^2+(15x-12x)-90=0
x(2x+15)-6(2x+15)=0
(x-6)(2x+15)=0
x-6=0
x=6 eq.1
2x+15=0
2x=-15(since length cant come in negative so it would not be the value of x)
Since x=6 according to eq. 1 ,therefore
Length =x+2
Length=6+2
Length=8..
