Answer 1

Answer:

Given:-

What is the perimeter of the rectangle whose length is 0.85 m and breadth is 70 cm.

To Find:-

Perimeter of the rectangle.

Note:-

●》Perimeter of the rectangle = 2 × ( Length + Breadth )

●》 For calculations, unit is need to be equal.

Solution:-

$\huge\red{Length = 0.85 m, Breadth = 70 cm, Perimeter = ?}$

[ Here, units are not same, let's make the length in also "cm"]

☆ We know that~

▪︎$1 m = 100 cm$

▪︎$0.85 m = 0.85 × 100 cm$

▪︎$0.85 m = 85 cm$

$\huge\pink{Now : Length = 85 cm, Breadth = 70 cm}$

[ Perimeter ]

☆ According to note first point~

▪︎$Perimeter \ \ of \ \ the \ \ rectangle = 2 × ( Length + Breadth )$

▪︎$Perimeter \ \ of \ \ the \ \ rectangle = 2 × ( 85 cm + 70 cm )$

▪︎$Perimeter \ \ of \ \ the \ \ rectangle = 2 × 155 cm$

☆ After doing calculations~

▪︎$Perimeter \ \ of \ \ the \ \ rectangle = 310 cm$

☆ Again in m~

▪︎$1 cm = \frac{1}{100} m$

▪︎$310 cm = \frac{310}{100} m$

▪︎$310 cm = 3.10 m$

Answer:-

Hence, Perimeter of the rectangle = 310 cm or 3.10 m
