Answer:
length= 17.5 m , breadth = 12.5 m
Step-by-step explanation:
The ratio of length : breadth = 7 : 5 = 7x : 5x ( x is a multiplier )
Then
2l + 2b = perimeter ( l is length, b is breadth )
2(7x) + 2(5x) = 60
14x + 10x = 60
24x = 60 ( divide both sides by 24 )
x = 2.5
Then
length = 7x = 7 × 2.5 = 17.5 m
breadth = 5x = 5 × 2.5 = 12.5 m
Answer:
3.87987×10^5
Step-by-step explanation:
surface area of the cylinder =2πrh+2πr²
=2*π*247*3+2*π*(247)²
=3.87987×10^5
The absolute value of a number can never be negative. That's because it represents the distance of a number from zero on a number line. The number

is

digits to the left of zero on a number line. So, the absolute value of

would be

.
