Step-by-step explanation:

28) Perimeter = 10 + 2 + (10 -2) + 3 + (8-2) + 1 + 8 + (1+3+2)

                       = 10 + 2 +  8 + 3 + 6 + 1 + 8 + 6

                        = 44 cm

29) Area = Area of upper block + area of middle block + area of the down block

= (10 * 2) + (2*3) + (1*8)

= 20 + 6 + 8

= 34 cm²

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
