Question

find the dimension of rectangle if its perimeter is 160 cm and its length is 10 centimetre more than its breadth.​

Answer 1

This is the answer of above question.

Answer 2

⚫Formula used

$perimeter \: of \: rectangle = \\ 2(l + b)$

⚫Given =

perimeter =160 cm

length =10+ breadth

⚫Explanation

↪By the conditions,

↪2(l+b) = 160cm

↪2((10 +b)+b) = 160

↪2(10+2b)=160

↪20+4b=160

↪4b=160-20

↪b=140/4

↪[b=35cm]_______________

➡therefor length will be,

↪2(l+35)=160

↪2(l)+70=160

↪2(l)=160-70

↪l=90/2

[l=45cm]__________

therefor the dimensions are length is 45 cm and breadth is 35cm of a rectangle •
