Answer 2

$\sf \Large Solution!!$

$\sf \large Given:$

$\sf \to Perimeter=46cm$

$\sf \to Breadth=9cm$

$\sf \large To\:find:$

$\sf \to Area\:of\:the\:rectangle$

Firstly, we will use the perimeter formula to find the length of the rectangle. After we find the length, we will apply the formula to find the area of the rectangle.

$\sf \to Perimeter=2(Length+Breadth)$

$\sf \to 46cm=2(Length+9cm)$

$\sf \to \dfrac{46}{2}cm=Length+9cm$

$\sf \to 23cm=Length+9cm$

$\sf \to Length=23cm-9cm$

$\sf \to Length=14cm$

$\sf \large Now,$

$\sf \to Area=Length\times Breadth$

$\sf \to Area=14cm\times 9cm$

$\sf \to Area=126cm^{2}$
