Answer 1

Hey Mate,

Here's your answer,

♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤♤

=> Given quatities,

=> Height = 5m

=> Lenght = 10m

=> Width = 15m

=> Area,

=> Area = Length × breadth × height

=> Area = 5m × 10m × 15m

=> Area = 750m

=> Perimeter,

=> Perimeter = Length + breadth + height

=> Perimeter = 5m + 10m + 15m

=> Perimeter = 30m

Answer 2

Answer:

perimeter = 50m

Area = 150m^2

Step-by-step explanation:

length of the room; l = 10m

breadth (or width) of the room; b = 15m

=> Perimeter = 2( l + b ) m

= 2( 10 + 15 ) m

= ( 2 × 25 ) m

= 50 m (ANS.)

=> Area = l × b

= ( 10 × 15 ) m^2

= 150 m^2 (ANS.)
