Question

Calculate the length of rectangle whose breadth is 14cm and area is 280cm2

Answer 1

$\sf \Large Solution!!$

$\sf \large Given:$

$\sf \to Breadth=14\:cm$

$\sf \to Area=280\:cm^{2}$

$\sf \large To\:find:$

$\sf \to The\:length$

$\sf \large So,$

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

$\sf \to 280\:cm^{2}=Length\times 14\:cm$

$\sf \to Length=\dfrac{^{20}\cancel{280}\:cm^{\cancel{2}}}{\cancel{14}\:\cancel{cm}}$

$\sf \boxed{\bigstar Length=20\:cm}$
