1. In Part A of this lab, you will measure the dimensions (length, width, diameter) of several geometric shapes. a. Using a ruler, you measure the length of a rectangle to be 12.75 cm and the width to be 3.64 cm. Calculate the area of this rectangle (show work), reporting your answer to the correct number of significant figures.

The area of this rectangle is 46.41 cm²

Step-by-step explanation:

Area of a rectangle:

The area of a rectangle of width w and length l is given by:

That is, the area of a rectangle is the multiplication of its width by its lengt.

In this question:

So

Width and length in centimeters, so the area is in square centimeters.

The area of this rectangle is 46.41 cm²

b

step-by-step explanation:

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
