Question

Please help me, i promise its worth it!!!

Answer 1

Step-by-step explanation:

Given,

Length= 4/3 x

Breadth= x

Perimeter=2(l+b)

55=2(4x/3+x)

55=8x/3+2x

55=(8x+6x)/3

55=14x/3

55×3=14x

165=14x

165/14=x

x=11.78

Hence,

Breadth=x=11.78

Length=4x/3=(4×11.78)/3=15.7067

Answer 2

$\\ \sf\longmapsto 2(L+B)=55$

$\\ \sf\longmapsto 2(\dfrac{4}{3}x+x)=55$

$\\ \sf\longmapsto \dfrac{8}{3}x+2x=55$

$\\ \sf\longmapsto \dfrac{8x+6x}{3}=55$

$\\ \sf\longmapsto \dfrac{14x}{3}=55$

$\\ \sf\longmapsto 14x=165$

$\\ \sf\longmapsto x=11.78$

$\\ \sf\longmapsto x\approx 12$

Now

• B=x=12
• L=4/3(12)=4(4)=16
