Question

20. The area of a rectangular garden
50 m long is 350 sq m. Find the width
of the garden
65 m
55 m
7 m
60 m​

Answer 1

Answer:

7m

Step-by-step explanation:

area = length x breadth

350 = 50 x breadth

breadth = 350/50 = 7m

Answer 2

Given :

• Length of a rectangular garden = 50 m
• Area of the rectangular garden = 350 m²

To find :

• Width of the garden

Knolwedge required :-

→ Formula of area of rectangle :-

• Area of rectangle = l × b

where,

• l = length of the rectangle
• b = breadth of the rectangle

Solution :

⠀⠀⠀⇒ Area = l × b

⠀⠀⠀⇒ 350 = 50 × b

⠀⠀⠀⇒ 350/50 = b

⠀⠀⠀⇒ 35/5 = b

⠀⠀⠀⇒ 7 = b

Breadth of the rectangular garden = 7 m

━━━━━━━━━━━━━━━━━━

Verification :-

Substitute the value of b in 350 = 50 × b

LHS = 350

Taking RHS,

⠀⠀⠀⇒ 50 × 7

⠀⠀⠀⇒ 350

RHS = 350

LHS = RHS

Hence, verified.

Know MorE :-

• Area of square = side × side
• Perimeter of square = 4 × side
• Diagonal of square = √2a
• Perimeter of reactangle = 2(l + b)
• Diagonal of rectangle = √l² + √b²
• Total surface Area of cuboid = 2(lb + bh + hl)
• Volume of cuboid =  length × breadth × height
• Perimeter of cuboid = 4 (length + breadth + height)
• Total surface area of cube = 6 × side²
• Volume of cube = side³
• Perimeter of cube = 12 × side
