Question

the length of a rectangle is 16 m less then twice it's breadth. if the perimeter of the rectangle is 100 m find the length and breadth
​

Answer 1

Resposta:

Hi, the answer is length = 28 and breadth= 22

Explicação passo-a-passo:

length = 2x-16

breadth = x

$2.[(x)+(2x-16)]=100\\2.(3x-16)=100\\3x-16=\frac{100}{2} \\3x=50+16\\x=\frac{66}{3} \\x=22$

so,

$l=2.22-16=28$
