3/4
The area of a rectangular aluminium sheet is
51/40
metres. Find the breadth of the sheet.
​

Answer 1

Answer:

Given:

✰ Area of a rectangular aluminium sheet = 3/4 m²

✰ The length of the sheet = 51/40 m

To find:

✠ The breadth of a rectangular aluminium sheet.

Solution:

Rectangle is a parallelogram with all its angles equal to 90°.

As we are already provided with the area of rectangle. So, here we will use formula of area of a rectangle to find its breadth. Putting the values in the formula and then doing the required calculations, we will easily find out the breadth of a rectangular aluminium sheet.

Let's find out...✧

✭ Area of a rectangle = l × b ✭

Here,

Area of rectangle is nothing but the area of the sheet which is in the shape of rectangle.

l is the length of a rectangular aluminium sheet.

b is the breadth of a rectangular aluminium sheet, which we need to find.

Putting the values in the formula, we have:

➤ 3/4 = 51/40 × b

➤ b = 3/4 × 40/50

➤ b = 3 × 10/50

➤ b = 30/50

➤ b = 3/5

∴ The breadth of a rectangular aluminium sheet = 3/5 m
