Question

length of a rectangle is 3m less than four times its breadth.if the primeter of the rectangle is 94m,find its length and breadth

Answer 1

Let breadth be x

Length= 4x

Perimeter of a rectangle =2(l+b)

=2(x+4x)

=2* 5x

=10x

Given, perimeter =94

10x=94

X=94/10= 9.4

Answer 2

$\bold{\boxed{Hoi!}}$

Let, Breadth = $\textbf{x}$
Length = $\textbf{4x-3}$

now,
we know that,
perimeter of rectangle = $\textbf{2(L+B)}$

but given that p = 94 m

therefore,

94 = 2(4x-3+x)

→ 94 = 2(5x-3)

→ 94/2 = 5x-3

→ 47+3 = 5x

→ 5x = 50

→ x = 50/5

→ x= 10

Therefore,

$\textbf{Length = 4x-3 = 40-3 = 37m}$

$\textbf{Breadth = 10m}$
