Question

If length of rectangle is 20 cm and breadth is 9 cm find area of rectangle and perimeter of rectangle

Answer 1

Answer:

l = 20 cm

b = 9 cm

Therefore by formula ,

area of rect. = length × breadth unit^2

= 20 × 9 cm^2 = 180 cm^2

perimeter of rect. = 2 ( l + b ) unit

= 2 ( 20 + 9 ) cm = 58 cm

hope you like the answer , stay blessed and love maths !!!

Answer 2

Gɪᴠᴇɴ :-

• Length (l) = 20 cm
• Breadth (b) = 9 cm

ᴛᴏ ғɪɴᴅ :-

• Area of Rectangle
• Perimeter of Rectangle

sᴏʟᴜᴛɪᴏɴ :-

We know that,

• Area of Rectangle = length × breadth

➭ Area = l × b

➭ Area = 20 × 9

➭ Area = 180 cm²

Perimeter of Rectangle = 2(length + breadth)

➭ Perimeter = 2(l + b)

➭ Perimeter = 2(20 + 9) = 2 × 29

➭ Perimeter = 58 cm

Hence,

• Area of Rectangle = 180 cm²
• Perimeter of Rectangle = 58 cm
