Hello Everybody
please solve this worksheet for me

Answer 1

1)

The altitude corresponding to side AD is 5 1/3 cm or 5.33 cm.

Step-by-step explanation:

The area of a parallelogram ABCD is:

AB * ha= 8 * 4  = 32 cm²

Also : AD * hb = 6 * hb = 32 cm²

hb = 32 : 6 = 5 1/3 = 5.33 cm.

2)

figure

3)

as we know that  

circumference of circle = pie×d

33=22/7×d

33×7/22=d

d=10.5 cm

So diameter of circle is 10.5 cm

4)

Least perimeter is obtained when rectangle is a square.

Now, side of the square = √36 = 6 unit

Now, perimeter = 4*sides = 4*6 = 24 unit
