Question

find the cost of painting wall of length 80 meters breadth 15 meters at the rate of rupees 12 per square meter​

Answer 1

Answer:

l=80m

b=15m

Area of painting wall (Rectangle)=l×b

80m×15m=1200m^2

If 1m^2 cost is rupees 12

Then 1200m^2 cost = 1200×12

=14400 rupees

Answer 2

Given:-

·length(l)=80m

·Breadth(b)=15m

·Rate=12₹per m²

$\rule{200}{1}$

To Find:-

→Total Cost of Painting the Wall?

$\rule{200}{1}$

AnsWer:-

→Area of The Painting=length×breadth

→Area of The Painting=l×b

→Area of The Painting=80×15

→Area of the Painting=1200m²

[°•°Rate per m²=12₹]

→1200m²=12×1200=Total Cost

→14400₹=Total Cost

•Hence,Total cost of painting is 14400₹•

$\rule{200}{2}$
