Answer 1

Answer:

700sq. m

Step-by-step explanation:

Area of rectangle = (l * b) = (20 * 15) square metres = 300 square metres. Area of four sides = {2 * (l + b) * h} = {2 * (20 + 15) * 10} square metres = (2 * 35 * 10) square metres = 700 square metres.

Answer 2

Answer:

700 square meters

Step-by-step explanation:

Area of roof = (l * b) = (20 * 15) square metres = 300 square metres.

Area of four walls = {2 * (l + b) * h} = {2 * (20 + 15) * 10} square metres = (2 * 35 * 10) square metres = 700 square metres.
