Question

the perimeter of a rectangle is 18, and the area is 14. What is the width?

Answer 1

2

Answer 2

l*w=14

Answer 3

2l+2w=18

Answer 4

l=7
w=2

Answer 5

solve these t2

Answer 6

perimeter of a rectangle=2(l+w)
2(l+w)=18
l+w=18/2
l+w=9

area of a rectangle= l*w
l*w=14

so,
l*w=14 and l+w=9
l=9-w

l*w=14
(9-w)*w=14
9w-w^2=14
w^2-9w+14=0
w^2-7w-2w+14=0
w(w-7)-2(w-7)=0
w-2=0,w-7=0
w=2,w=7

so,length=7 and width=2
