A length of a rectangle i 370mm correct to 2 ignificant figure the width i 19. 4mm correct to 1 decimal place. What the lower bound of the area of the rectangle?

Respuesta :

The lower bound of the area of the rectangle is  7062.75 [tex]mm^{2}[/tex].

What is the Lower bound and Upper bound?

Lower Bounds - The lowest value that would be utilized to round a number to the previously estimated value is known as the lower bound.

Upper Bounds - The lower value that would be used to round a number to the next expected value is known as the upper bound.

Given, length = 370 mm

           width = 19.4 mm

First, we consider length = 370 mm, then

The upper bound for length = 375 mm

And, the lower bound = 365 mm

Second, we consider  width = 19.4 mm, then

The upper bound for width = 19.45 mm

And, the lower bound = 19.35 mm

So, the area of the given rectangle is:

Area =  length * width

Using lower bounds dimensions for both length and width, then

Area = 365*19.35 [tex]mm^{2}[/tex]

        = 7062.75 [tex]mm^{2}[/tex]

Therefore, the lower bound of the area of the rectangle is  7062.75 [tex]mm^{2}[/tex]
