Answer:

Q2

(a) A = 150 cm²,  Peri = 50 cm (b) A =  64 cm², Peri = 32 cm (c) A = 74 cm², Peri = 33 cm

Step-by-step explanation:

From the pdf file attached,

Q1.

If the area of each square is 1 cm³, Therefore,

The length of each square in the diagram is 1 cm.

To draw the a rectangle on the diagram such that the perimeter is 12 cm.

We have to count 4 squares from left to right, and then, 2 squares from up to down

As shown is the diagram attached.

Q2

(a) Area = (l+b)

     Where l =  15 cm, b = 10 cm.

     Area = 15×10

     Area = 150 cm²

     While

     Perimeter = 2(l+b)

     Perimeter. = 2(15+10)

     Perimeter. = 2(25)

     Perimeter. = 50 cm

(b)  Area = L²

     Where L = 8 cm

     Therefore,

      Area = 8²

      Area = 64 cm²

      While

      Perimeter =  4L

      Perimeter = 4×8

      Perimeter = 32 cm

(c) Area of the compound shape = (5×4)+(6×9)

    Area of the compound shape = 20+54

    Area of the compound shape = 74 cm²

    While

    Perimeter = 10+9+6+4+4

    Perimeter = 33 cm
