The length of diagonal EK is sqrt(5^2 + 4^2) ≈ 6.403m
Hence perimeter = 2*(12 + 6.403) → 36.8 m (to the nearest tenth of a metre)
The correct answer is c (2x+10)
I think her error was that she multiplied he numbers wrong
Answer:
y=40.5
Step-by-step explanation:
you need to get y out of a fraction, to do so multiply by the denominator on both sides
3(2/3y) = 3(27)
then divide to solve for y
2y = 81
y=40.5
The volume in cubic meter of the cuboid with the dimensions length = 12 m , breadth = 10m, height = 4.5 m is 540 m³
<h3 />
<h3>Volume of a cuboid:</h3>
where
l =- length
w = width
h = height
Therefore,
l = 12 m
w = 10 m
h = 4.5
v = 12 × 10 × 4.5
v = 120 × 4.5
v = 540 m³
