Answer:
The perimeter of the square is 16 √ 5
The area of the square is 8√5
Step-by-step explanation:
To solve this you first need to solve 4√5 which is 8.94. This made the perimeter 35.76 which is equaled to 16√5. The area is 17.88 which is the same as 8√5.
Step-by-step explanation:
So, cost of 6.5 kg of apples is Rs. 520 and we need to find cost of one kg apples.
<h2>It can be done just by applying Unitary Method!</h2>
So,
6.5 kg -- Rs. 520
1 kg -- Rs.(520/6.5) = Rs.80
<h3>So, cost of 1 kg apples is Rs.80.</h3>
Answer:
4.5 pounds
Step-by-step explanation:
Convert them both to improper equations.
2 3/4 = 11/4
1 3/4 = 7/4
Then add.
11/4 + 7/4 = 18/4
Then simplify.
18/4 = 4 2/4 = 4.5
