Question

18. The area of a rectangular aluminium sheet is
51
metres. Find the breadth of the sheet
square metres. The length of the sheets
10​

Answer 1

Answer:

the breadth of the sheet

square metres = 5.1

Step-by-step explanation:

area of rectangle = length * breadth

51 = 10* breadth

51/10 = breadth

5.1 = breadth

Answer 2

Answer :-

⑅ The breadth of aluminium sheet is 5.1 m

Correct Question :-

18. The area of a rectangular aluminium sheet is

51m². The length of the sheet is 10m. Find the breadth of the sheet in metres.

Given :-

✧ The length of aluminium sheet (l) = 10m

✧ The area of aluminium sheet (a) = 51m²

To find :-

◍ The breadth of aluminium sheet.

Solution :-

In the question, the length and area of aluminium sheet is given and we have to calculate its breadth.

Area of aluminium sheet is the product of its length and breadth

$\mapsto \: \tt{Area \: \: of \: \: aluminium \: \: sheet = Length \times Breadth}$

Substituting the values we have,

$\tt{=> 51{m}^{2} = 10m \times b} \\ \\ \tt{=> \frac{51 {m}^{2} }{10m} } = b \\ \\ \tt{ = > 5.1m = b}$

Hence, the breadth of the aluminium sheet = 5.1 m.

• Area of square = (Side)²

• Area of rectangle = Length × Breadth

• Perimeter of square = 4 × side

• Perimeter of rectangle = 2(Length + Breadth)

• Area of rhombus = 1/2 × First Diagonal × Second Diagonal

• Perimeter of rhombus = 4 × Side

• Area of parallelogram = Base × Height
