has with the only 30 m.barbed wire , he fences three sides of garden
letting compound wall of his house act as the fourth
fence . Find its length and breadth.​

Answer 1

Step-by-step explanation:Let the length of one side be x metres and other side by y metres. Then,x+y+z=30⇒y=30−2xArea of the vegetable garden =100m 2 ⇒ xy=100⇒x(30−2x)=100⇒30x−2x 2 =100⇒15x−x 2 =50⇒x 2 −15x+50=0⇒x 2 −10x−5x+50=0⇒(x−10)(x−5)=0⇒x=5,10When x=5 we havey=30−(2×5)=20When x=10,we havey=30−(2×10)=10Hence, the dimensions of the vegetable garden are 5m×20m or 10m×10mplease mark me as brainliest and follow me
