Step-by-step explanation:
⚫Formula used
\
⚫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 •
