Question

The length of a is rectangle 6 cm more than it’s breadth.if the perimeter of rectangle is 84 cm ,then find breadth and length and also find its area

Answer 1

$\:\: \underline{\underline{\bf{\large\mathfrak{~~Given~~}}}}$

➜breadth(b)=X(let)

➜length(l)=(X+6)cm

➜perimeter (p)=84

$\:\: \underline{\underline{\bf{\large\mathfrak\red{~~Solution~~}}}}$

so..

2(X+X+6)=84

➜2x=42-6

➜x=38/2

➜x=19

therefore.... length=19+6=25cm

breadth=19cm

therefore..area=lenth×breadth=25×19=475cm²
