One side of a rectangle is #4# #ft# shorter than twice the other side. What are the sides if the area is #96 # #ft^2#?

Answer 1

Violet Aldrich

Length =12 ft breadth = 8ft

let length = xft breadth= x-4 ft

By the condition Area=#x^2-4x=96# #x^2-12x+8x-96=0# #x(x-12)+8(x-12)=0# #(x-12)(x+8)=0# so Length =12 ft breadth = 8ft

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
