Question

the area of the rectangle is (x2 + 12x + 35) sq units and its breath is (x+7) what is the length

Answer 1

Answer:

area of the rectangle( x^2+12x+35) sq unit

breadth=(x+7)unit

length=area/breadth

=(x^2+12x+35)/(x+7) unit

=(x^2+7x+5x+35)/(x+7) unit

={x(x+7)+5(x+7)}/(x+7) unit

=(x+7)(x+5)/(x+7) unit

=(x+5)units

si length of the rectangle (x+5) unit
