Question

The area of a rectangular piece of cardboard is 80 sq.cm.Find its length if its breadth
is 6 1/4 cm?

Answer 1

Answer:

$12\frac{4}{5}$ cm

Step-by-step explanation:

Given:

• Area of the rectangular piece of cardboard = 80 cm²
• Breadth of the cardboard piece = $6\frac{1}{4} =\frac{25}{4}$ cm

To find:

• Length of the cardboard piece (l)

Area of a rectangle = Length of the rectangle×Breadth of the rectangle

Substituting the above values:

80=l×$\frac{25}{4}$

l=$80 \times \frac{4}{25}$

l=$\frac{320}{25}$

l=$\frac{64}{5}$

l=$12\frac{4}{5}$

The length of the rectangular cardboard piece is equal to $12\frac{4}{5} \ cm$

The area of a rectangular piece of cardboard is 80 sq cm.Find its length if its breadth

is 6 1/4 cm.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$\purple{\mathbb{ANSWER:-}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Given:-

Area of rectangular cardboard = $\red{80 sq cm}$

Breadth = $\red{6 \frac{1}{4} cm = \frac{25}{4} cm}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

To find:-

Length=?

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Formula used:-

Area of rectangle =$\red{ Length \times Breadth}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Putting Values:-

$⇝80 = Length \times \frac{25}{4} \\⇝ 80 \times \frac{4}{25} = Length \\⇝ 16 \times \frac{4}{5} = Length \\⇝ \frac{64}{5} = 12 \frac{4}{5} = Length \\ ⇝\red{Length = 12 \frac{4}{5}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Final Answer:-

∴ Length = ${\boxed{\blue{\bf{12 \frac{4}{5} cm}}}}$
