Answer:
Step-by-step explanation:
x²/2 =271 represents the situation where taking length twice as breadth and area as 271 ft² .
Area of a figure is the amount of space acquired by the figure
Area of a rectangle=Length x breadth
length=x
breadth=x/2
Area of rectangular lawn=lxb
=x.x/2
But as per question,
Area=271 ft²
⇒x²/2=271 1
⇒x=23.28 ft²
Therefore, x²/2 =271 represents the situation where taking length twice as breadth and area as 271 ft² .Value of x i.e. length is 23.28 ft²

Tan 37,4 = opposite/adjacent
tan 37,4 = x/12,8
• then multiply both sides by 12,8
12,8tan 37,4 = x
Therefore x = 9, 79 x 100
= 97, 86
= 100
( I guess that’s how you can round it to the nearest hundred, please correct me if I’m wrong)
Second one:
Answer:
8/75
Step-by-step explanation:
We conclude that the equation evaluated in t = 6 and u = 14 is equal to 412.
<h3>
How to evaluate an expression?</h3>
Here we have an expression with two variables, t and u.
6t - 32u
And we want to evaluate it in t = 6 and u = 14.
This means that we need to replace the two variables in the equation by the given numbers, so we replace the "t" with a 6, and the "u" with a 14, doing that we get:
6*6 - 32*14
Now we can solve that:
6*6 - 32*14
36 - 448 = 412
We conclude that the equation evaluated in t = 6 and u = 14 is equal to 412.
