Answer:
a=88
b=82
Step-by-step explanation:
perimeter=2(l+w)
302=2(l+63)
302=2l+126
2l=176
l=88
A=l×w
8118=99×82
w=82
Well if I did my math correctly I do believe the perimeter should be 392 ft.
6÷2.5= 2.4
2.4×35=84
8÷2.5= 3.2
3.2×35=112
84×2
112×2
_____
392
you mult. by 2 because it's a room which usually has four walls and I imagined it being a rectangle.
P of a rectangle= 2l + 2w
P = 2(48) + 2(20)
P= 96 + 40
P= 136m
The length of the rectangle is 136 meters.
I hope that helped.
