add them

280+300

580

now cost is 12 per m sq so

The Brainliest Answer!

b= 15 m

h= 4 m

First we find the area of floor

=>20x15

=>300 m²

Then, we find area of walls

=>2(20x4) + 2(15x4)

=>2(80 + 60)

=>280 m²

Add both to get total area

=>300+280 = 580 m²

Multiply total area and cost per m²

=>580 x 12

=>Rs. 6960

Hope it'd be useful.Please choose it the brainliest answer.

CHEERS!
