Let the width be x, the length is then 3x-10
Area of a rectangle is length times width: x(3x-10)=77 => 3x^2-10x-77=0
Factor this quadratic equation: (x-7)(3x+11)=0 =.x=7 or x=-11/3
width cannot be negative, so the only answer is x=7
width is 7m, length is 11m

Answer:
452.16 units^2
Step-by-step explanation:
Given
Radius = r= 6 units
The formula for finding the surface area of a sphere is:
In the formula, π is taken as 3.14.
So, the surface area of the given sphere is 452.16 units^2 ..
