Question

What is the perimeter of a rectangle with length
0.42 & breadth 31.5 m
​

Answer 1

$GIVEN:\\Length \: = 42m \:\\ breadth= 31.5 m$

$To \: Find:$

$perimeter \: of \: the \: rectangle$

$Solution:$

$length= 42m \\ breadth = 31.5m \\ we \: know \: area \: of \: rectangle \\ = 2(length + breadth)$

$area = 2(42 + 31.5) \\ area = 2 \times 73.5 \\ area \: = 147m$

$area \: of \: the \: rectangle \: is \: 147m \: \\ \\ \\ hope \: this \: help \: you$

Answer 2

$perimeter \: \: of \: \: rectangle \: = 2(l + b) \\ = > 2(0.42 + 31.5) \\ = > 2 \times 31.92 \\ = > 63.84 {m}^{2}$
