Answer 1

Answer:

length of carpet = 29cm

Width= 11cm

Let the width be x cm then the length will be (3x-4)cm when the length becomes 7cm long, it will be (3x-4+7)cm=(3x+3)cm and the width becomes 2cm short, it will be(x-2)cm according to problem = 2{(3x+3)+ (x-2)=90 = 2(3x+3+x-2)=90 - 24x+1)]=90 - 8x+2=90

8x=88 = X311 hence,

Width will be 11 cm

Length will be 29 Cm

Hope it helps you
