Question

The area of a rectangular sheet is 500 cm2. If the length of the sheet is 50 cm, what is its width? Use this width to find the perimeter of the rectangular sheet and select its correct choice from belowImmersive Reader

Answer 1

A=(l)(b)
500=50b
b=500/50
b=10
P=2(l+b)
P=2(50+10)
P=2(60)
P=120

Answer 2

Correct Question :

The area of a rectangular sheet is 500 cm². If the length of the sheet is 50 cm, what is its width? Use this width to find the perimeter of the rectangular sheet.

Answer :

• The width of the sheet = 10 cm
• The perimeter of the rectangular sheet is 120 cm

Step-by-step explanation :

To Find,

• The width of the sheet
• The perimeter

Solution,

Given that,

• The area of the sheet = 500 cm²
• Length = 50 cm

As we know that,

Width = Area / Length ..... Case 1

Therefore,

» 500 / 50

» 10

∴ Hence, Width of achieving sheet is 10 cm.

Now, perimeter of the sheet

As we know that,

Perimeter = 2 ( Length + Breadth ) ..... Case 2

Therefore,

» 2 ( 50 + 10 )

» 2 × 60

» 120

∴ Hence, Perimeter of the rectangular sheet is 120 cm.
