Question

THE
LENGTH OF A RECTANGLE
TWICE
THE WIDTH. IF THE
PERIMEOER IS 20cm. FIND THE
WIDTH​

Answer 1

Answer:6.6c.m(approx)

Step-by-step explanation:let the width be x c. M

Then, length=2x c. m

Perimeter=20c.m

Perimeter of rectangle=2(l+b)

20c.m=2(x+2x)

20c.m=2(3x)

20c.m=2*3x

20c.m=6x

20/6=x

3.3333c.m=x

X=3.3333c.m

WIDTH=2X=2*3.3333

=6.6666c.m

Width=6.6 c. m(approx)

Answer 2

Answer:

For a rectangle

Length=2×width

perimeter=20 cm

2(length+width)= 20 cm

2×width+width =10 cm

Width=10/3 = 3.33 cm
