Question

the area of a rectangle is x²+7x+12.if it's breath is (x+3),then find its length​

Answer 1

Answer:

length = (x+4)

Step-by-step explanation:

Area = Length x Breadth

=> x^2 +7x +12 = (x+3) * length

=> x^2 +7x +12 / (x+3) = length

=> x^2 + 4x + 3x +12 / (x+3) = length

=> x(x+4) + 3(x+4) / (x+3) = length

=> (x+4) + (x+3) / (x+3) = length

=> length = (x+4)
