Question

If length of a rectangular floor is 7.5m and breadth is 6cm. Find the area and perimeter of tha rectangle floor​

Answer 1

Answer:

rectangle formula=lxb

Step-by-step explanation:

so length =7.5cm

breadth=6cm

area of rectangle=7.5x6

=40cm

Answer 2

Given:

• Length of rectanglur floor- 7.5m
• Breadth of rectangular floor- 6cm

To find:

• Area of the rectangular floor
• Perimeter of rectangular floor

Required Formulae:

$\fbox{Perimeter of Rectangle- 2×(l+b)} \orange \bigstar \\\fbox{Area of Rectangle- l×b} \orange \bigstar$

Here,

• l denotes to length.
• b denotes to Breadth

Solution:

• First, we check the values are in same unit.

So,

Change it in metre(m).

Here,

We use formula:

$\boxed {\rm{1cm = \frac{1}{100} m}} \purple \bigstar$

$\rm{ 6 \: cm = \frac{6}{100} } \\ \rm { \: \: \: \: \: \: \: \: \: \: \: \: \boxed {\rm{= 0.06m}}} \blue\bigstar$

• Let's put the values to find Perimeter.

$\rm{Perimeter \: of \: Rectangle = 2×(l+b)} \\\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \rm{= 2(7.5 + 0.06)m} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \rm {= 2(7.56)m} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed {\frak{15.12m}} \pink\bigstar$

• Now, find the area by putting values.

$\rm{Area \: of \: Rectangle = l×b} \\\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \rm{=(7.5 \times 0.06)m} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \boxed {\frak{0.45m²}} \pink\bigstar$

• The perimeter of the rectangular floor is 15.12m
• The area of the rectangular floor is 0.45m²
