Answer 1

Solutions :-

Given :
Length = 30 m 75 cm = 30.75 m
Breadth = 80 cm = 0.8 m

Find the area of carpet :-

Area of rectangle = Length × Breadth sq. units
= (30.75 × 0.8) m²
= 24.6 m²

Find the cost :-

1 m² = Rs 150
24.6 m² = Rs (150 × 24.6) = Rs 3690

Hence,
Its cost = Rs 3690

• Length ( l ) = 30m and 75cm.
• Breadth ( b ) = 80 cm.

Both , l and b in m ;-
• L = 30.75 m.
• B = 0.80 m.

Now ,
Finding the area of carpet ;-

We know that ;-
• Area of Rectangle = Length ( l ) × Breadth ( b ) sq. units.

So ,
=> ( 30.75 × 0.80 )^2 = 24.6m^2

Now ,
Finding the Cost ;-

Given that ;-
1 m^2 = ₹ 150

Then ,
24.6 m^2 = ₹( 150 × 24.6 ) = ₹ 3690.
