1.	Tha perameter of a rectangular sheet is 200 cm.if the length is 15 cm.find it's breadth.also fine the area
Answer» Step-by-step EXPLANATION: $perimeter \: of \: rec = 2(l + b) \\ \\ 2(15 + b) = 200 \\ \\ 30 + 2b = 200 \\ \\ 2b = 200 - 30 \\ \\ b = 170 \div 2 \\ \\ b = 85 \\ area \: of \: rec = lenght \: \times breadth \: \\ \\ 15 \times 85 \\ \\ 1275$
