Question

The length of rectangle is twice its breath if area of the rewctangle 417

Answer 1

here,

let, breadth of the rectangle(b) be x m

length of the rectangle(l)=2x m

now,

area of the rectangle(a)=417 sq. m

or, l*b=417

or, 2x*x=417

or, x=(208.5)^1/2

x=14.44 m

again,

length of the rectangle(l)=2x=2*14.44=28.88 m
