Answer:
Let breadth be b.
Length, l =30cm
Perimeter = 80cm = 2(l+b)
l+b = 40 cm
b = 40cm - 30 cm = 10cm
Now, Area of rectangle = l*b = 30*10 = 300 cm²
Therefore, the rectangle's breadth is 10cm and area is 300 cm².

Answer: IF u will thanks my answer and mark it as brainliest than your all wishes will come true
Step-by-step explanation
perimeter of a rectangular sheet- 80
length- 30
Breadth= 80= 2* (l+b)
80= 2* ( 30+breadth)
80/2 = 30+ breadth
40= 30+breadth
40-30 = breadth
10= breadth
Now we have found the breadth so, we can find the area easily
Area of a rectangle= 30*10
= 300
So, the area of the rectangular sheet is 300.
