Question

the perimeter of a rectangle is 42 M and its breadth is 7.4 M find the length and the area of the rectangle

Answer 1

here is your answer to find out area

Answer 2

$\underline{ \text{Perimeter \: of \: any \: rectangular \: shaped \: thing = 2(length \: + \: breadth}}$





Here,
Perimeter of Rectangle = 42m
Breadth of Rectangle = 7.4m





Applying formula,

➡ 42 m = 2( 7.4 + length )

$= > ( \frac{42}{2} ) \: m = 7. 4 + length \\ \\ \\ = > 21 = 7.4 + length \: \\ \\ \\ = > 21 - 7.4 = length \\ \\ \\ = > \boxed{ \bold{13.6m \: = length}}$






Area of Rectangular shaped body = length × Breadth


So,




Area of this Rectangle = 13.6 m × 7.4 m

Area of this Rectangle = 100.64 m²
