4. Pak Kamto has a rectangular piece of land. The width of the land it has is 5 meters shorter than its length. Pak Sarif's circumference is 50 meters. What is the length and width of Kamto's land?

5. If point b is shifted by t (6 -2) to b '(0,1) then point b is

Answer 1

1) 6 meters = 600 cm

  600 ÷ 30 = 20cm

2) 2 decades = 10x2 = 20 years

                      20 + 3 = 23

   7 windu = 8x7 = 56 years

              56 - 23 = 33

3) K = 2 × π × r

       = 2 × 3.14 × 20

       = 6.28 × 20

       = 125.6 cm

4) P = 15 m

l = 15 - 5

 = 10 m

Then 2 × (15 + 10)

= 2 × 25

= 50

So the answer is length = 15 m and width = 10 m

5) b (x, y) + (6, -2) = (0,1)

x + 6 = 0

x = -6

y - 2 = 1

y = 3

point b (-6.3)
