Question

. The length and breadth of a rectangle are 4.5 m and 175 cm respectively. Find:
(i) Perimeter of the rectangle (ii) Area of the rectangle
the​

Answer 1

Answer: Perimeter = 12.5 and Area = 7.875 sq.cm

Step-by-step explanation:

First convert cm to m , hence 175 cm =1.75 m

Perimeter of rectangle  = 2(l+b)

= 2(4.5+ 1.75) = 2(6.25) =12.50

Hence perimeter of given rectangle = 12.50 cm

Area of rectangle = l*b

=4.5*1.75 = 7.875 sq.cm

Answer 2

$\boxed{\sf{ \rm{\blue{Perimeter = 12.5m}}}}$

$\boxed{\sf Area = 7.875m^2}$

Step-by-step explanation:

${\underline {\bf{\huge {\green{Given}}}} }$

$\bf \: Length\to 4.5m$

$\bf \: Breadth \: \to175cm$

First let us convert Breadth to meters

To convert centimeter to meter we have to divide 175 by 100.

$\implies \bf \large \frac{175}{100}$

$\implies \bf \large1.75m$

New breadth = 1.75 m

We know that perimeter of a Rectangle =

${\huge {\boxed {\bf{Perimeter = 2 (Length + Breadth)}}}}$

Length = 4.5m

Breadth = 1.75m

$\boxed{\sf{ \rm{\blue{Perimeter = 2 \times (Length + Breadth)}}}}$

$\boxed{\sf{ \rm{\blue{Perimeter = 2 \times (4.5 + 1.75)}}}}$

$\boxed{\sf{ \rm{\blue{Perimeter = 2 \times 6.25 }}}}$

$\boxed{\sf{ \rm{\blue{Perimeter =12.5 m}}}}$

♧________________________________♧

$\boxed{\bf {\huge{Area = Length \times Breadth}}}$

Length = 4.5m

Breadth = 1.75m

$\boxed{\sf Area = 4.5 \times 1.75}$

$\boxed{\sf Area = 7.875m^2}$
