Draw dream house and find the perimeter and area.

From the figure we are able to find the world of the roof as 15*1=15

because it's a square. Perimeter of the roof is 2(15+1)=32 cm.

Area of 1 window=1*1=1

and therefore the perimeter of 1 window is 1*4=4 cm.

Area of 1 door=1*4=4

and therefore the perimeter of 1 door is 2(1+4)=10 cm.

Door is of shape rectangle , windows are of square and also the roof is of rectangle.

In millimeters

Area of roof=15*10=150 millimeters.

Area of 1 window=1*10=10 millimeters.

Area of 1 door=4*10=40 millimeters.

Perimeter of roof=32*10=320 millimeters.

Perimeter of 1 window=4*10=40 millimeters.

Perimeter of 1 door=10*10=100 millimeters.
