Question

The height of rectangular room is 8m and its perimeter of the floor is 20m. Find its Area
four walls of the room..​

Answer 1

Answer:

height =8 m perimeter =20m so area =?

Step-by-step explanation:

base 20*2/8 =40/8=5

base=5m

therefore area b*l =5*8 =40 m=area

Answer 2

*Answer*

16m

Step-by-step explanation:

Perimeter =2(l+b)

20=2(8+b)

20=16 + 2b

20-16 =2b

4 =2b

B=4/2 = 2m

Area = l(b)

Area =8 (2)

= 16m
