Answer:
256 m and 3840 m²
Step-by-step explanation:
The 3 part of the ratio represents 48 m , then
48m ÷ 3 = 16 m ← value of 1 part of the ratio, so
5 parts = 5 × 16 m = 80 m
Then breadth = 48 m and length = 80 m
perimeter = 2l + 2b = 2(80) + 2(48) = 160 + 96 = 256 m
area = lb = 80 × 48 = 3840 m²
Hello!
First of all, let's undo the parentheses.
8x+6=18
Now we subtract 6 from both sides.
8x=12
Finally, we divide both sides by 8.
x=1.5
I hope this helps!
