7. Find the perimeter of rectangle whose length is
28 cm and breadth is 17 cm.​

Answer 1

Perimeter of rectangle=2(l+b)
=2(28+17)
=2×45
=90cm

Answer 2

Step-by-step explanation:

We Have :-

$a \: rectangle : - \\ \\ \\ length \: = \: 28 \: cm \\ \\ \\ breadth \: = \: 17 \: cm$

To Find :-

$perimeter \: of \: rectangle$

Formula Used :-

$perimeter \: of \: rectangle \: = \: 2(length + breadth)$

Solution :-

$perimeter \: of \: rectangle \: = \: 2(length + breadth) \\ \\ \\ putting \: the \: values \\ \\ \\ perimeter \: of \: rectangle \: = \: 2(28 + 17) \\ \\ \\ perimeter \: of \: rectangle \: = \: 2(45) \\ \\ \\ perimeter \: of \: rectangle \: = \:90 \: cm$
