Question

length of a rectangle is 3 metre less than four times its breadth if the perimeter of the rectangle is 94 metre find its length and breadth​

Answer 1

Let, Breadth = \textbf{x}x

Length = \textbf{4x-3}4x-3

now,

we know that,

perimeter of rectangle = \textbf{2(L+B)}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}Length = 4x-3 = 40-3 = 37m

\textbf{Breadth = 10m}Breadth = 10m

Answer 2

$\huge\bold\underline\fbox{Answer}$

Given,

Perimeter = 94 m

Let the breath of rectangle be x,

Then length = 4x-3 m

Perimeter of rectangle = 2*(l+b)

94 = 2*(4x-3+x)

94 = 2*(5x-3)

94 = 10x-6

94+6 = 10x

10x = 100

x = 100/10

x = 10

Therefore, the length is 10x-3 = 27 m

And breadth is x = 10 m
