Question

the perimeter of a rectangle is 13cms.and the width
$2 \frac{3}{4} cm find \: length \: of \: the \: rectangle$

Answer 1

Hello!

_________________________


Perimeter = 2 (length + breadth)

= Perimeter = 13 cm

= Length = x

= Breadth = 2 x 3/4 = 11/4 cm = 2.75 cm

=> 13 = 2 (x + 2.75)

= 13 = 2x + 5.5

= 2x = 13 - 5.5

= 2x = 7. 5

= x = 7. 5 /2

= x = 3. 75 cm


Therefore, the length of the rectangle is 3. 75 cm.


I hope it helped.

Thank You!
