A rectangle has a width of 4 units and a length of m units. Write an expression for the area of this rectangle.

What is the area of the same rectangle if m is:

3 units
2.2 units
1/5 units
Could the area of this rectangle be 11 square units? Why or why not?

The area of rectangle is 4*m square unit.

Step-by-step explanation:

So,

        Area of rectangle (A)= length * width

                                         = 4 *m sq. unit

              Area= 4*3 square unit.

                     = 12  square unit.

              Area= 4*2.2 square unit.  

                     =8.8 square unit.

                Area= square unit.

                       = 0.8 square unit.    

                       m= unit

                          = unit

                          =2.75 unit

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
