Answer:
The area of the square is 85 units^2
Step-by-step explanation:
Okay, here in this question, we are interested in calculating the area of the unknown square.
Kindly note that, since each of the other shapes are squares too, it means that the length of their sides is simply the square root of their areas.
Thus, the length of the squares are ;
√35 units and √50 units respectively
Now to find the area of the larger square, we employ the use of Pythagoras’ theorem which states that the square of the hypotenuse is equal to the sum of the squares of the two other sides
Let’s call the unknown length X
x^2 = (√35)^2 + (√50)^2
x^2 = 35 + 50
x^2 = 85
x = √85 units
Now as we know that the area of a square is simply the length of the side squared,
The area of the biggest square is simply (√85)^2 = 85 units^2
43/5 this is an improper fraction so we will convert it to a mixed number...
(40+3)/5
8+3/5
So he can make 8 complete groups and will have 3 left over.
Answer:
Your answer is A.
Step-by-step explanation:
When finding the area, you multiply π (3.14) and the radius (r). Then, you square the product (x2).
So, it is A = πr2
Hope this helps! :)
