Question

the length of a rectangular frame is 13/2cm and the breadth is 2 cm less than the length find the perimeter of the rectangular frame also find the area of the rectangular frame ​

Answer 1

Answer:

Breadth =

$\frac{13}{2} - 2 = \frac{13 - 4}{2} = \frac{11}{2} cm$

‎ ‎

‎ ‎

Area of the frame -

$\color{black}\boxed{\colorbox{saffron}{Area - length×breadth}}$

$\frac{13}{2} \times \frac{11}{2} = \frac{143}{4} {cm}^{2}$

‎ ‎

‎ ‎

Perimeter of the frame -

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2(length+breadth) }}$

$2( \frac{13}{2} + \frac{11}{2}) \\ \\ = 2( \frac{24}{2} ) \\ \\ = 24cm$
