Step-by-step explanation:

perimeter of rectangle-l*b

=2×2.5=5.0

Cost of glass at 1m²=1.50

cost of glass at 5m²=5×1.50=7.50m²

Answer 2

$\sf \: Answer$

Length of a window = 2.5 m

Breadth of a window = 2 m

Area of a window = L × B = 2.5 × 2 = 5 m²

Cost of the glass per sq. metre = ₹ 1.50

1 m² = ₹ 1.50

5 m² = 5 × 1.50 = ₹ 7.5
