Answer:
Perimeter of rectangular sheet → 2(L+B)
180cm → 2(L+30cm)
180cm → 2L+60cm
180-60/2 cm → L
60cm → L
Area of rectangular sheet → L×B
60×30 cm²
1800cm²

Answer:
"let the length be x
Perimeter = 2(L + B)
but p = 180cm (given)
180 = 2(x + 30)
180 = 2x + 60
2x = 180 - 60 = 60
x = 60/2 = 30
area = L × B
= 30 × 30 = 900cm^2"
