Area of cortyard= L×B

6×4.5=27m²

Area of mattress= 3.5×2.5=8.75m²

Area of courtyard wothout mattress= Area of coutyard - Area of mattress

27-8.75=18.25m²

Hope it helps you.....

Answer 2

Answer:

area of the courtyard = l×b

6m×4.2m= 25.2sq.m

area of the mattress = l×b

3.5×2.5=8.75

area of the courtyard without the mattress=

25.2-8.75= 16.45

thus the area of the courtyard without the mattress will be 16.45sq.m
