Find the area and perimeter of a rectangle, whose length = 8.5 cm, breadth = 4.5 cm
Answers
Answer: perimeter= 26cm, area= 38.25 cm sq
Step-by-step explanation:
Perimeter=2[8.5+4.5] = 2 x 13 = 26cm
Area= 8.5 x 4.5 = 38.25 cm sq.
pls mark brainiest if this helps you
Answer:
If PS = I and PQ = b
perimeter of the rectangle = PQ + QR +RS + SP
= b + I + b + I
= 2b + 2I
Again,
ABCD is rectangle. We Know that the opposite sides of a
rectangle are equal.
Here draw a rectangle
AB = CD = 5cm and BC = AD = 3 cm
So, the perimeter of the reangle ABCD = AB + BC + CD
AD = 5cm + 3cm + 5 cm + 3 cm = 16
If can be written as 5 cm + 5cm + 3cm + 3cm
= ( 2 × 5 ) cm + ( 2 × 3 ) cm
= 2 ( 5 + 3 ) cm
= 2 × 8 cm
= 16cm
