Answer:
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

Answer:
length = 35m
Area of the rectangle = 35 × 30 = 1050m²
Step-by-step explanation:
perimeter of a rectangle = 2(l+b) = 130m
breadth = 30m
2(l+b) = 130m
2(l+30) = 130
2l + 60 = 130
2l = 130 - 60
2l = 70
l = 70/2
length = 35m
Area of a rectangle = lb = l×b
35 × 30 = 1050m²
