Question

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

Answer 1

Answer:

P=12, P=8,8, P=4,5

Step-by-step explanation:

P=4*m, P=area

If m=3, P=4*3=12

if m=2,2 P=4*2,2=8,8

if m=1/5 P=4*1/5=4/5

if P=11 then 4*m=11, m=11/4

The area of ​​the rectangle is 11 if m =11/4

Answer 2

Answer:

Step-by-step explanation:

hello :

the area of this rectangle : A= 4×m

for m =3   A= 4×3 =12 U

for m =2.2   A= 4×2.2 =8.8 U

for m =3   A= 4×1/5 =4/5= 0.8 U

the area of this rectangle be 11 square units when : 4m =11²

m = 11²/4 U +30.25 U
