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
