Answer:
Area of square is 625 cm².
Explanation:
Side (length) = 25 cm
As we know, all the sides of the square are equal.
Further,
Area of the square = (side) ²
Area = ( 25 )²
Area = 625 cm²
Therefore, area of the square is 625 cm².

Step-by-step explanation:
because the circumference
Answer:
The first thing we need to do is find the area of the rectangle...
<em>l x w = A</em>
<em>7 x 8 = 56</em>
So the area of the first rectangle is 56m.
Now we multiply each dimension by 5...
<em>8 x 5 = 40</em>
<em>7 x 5 = 35</em>
So, now the width is 40m and the length is 35m,
Then, find the area of the new rectangle...
<em>35 x 40 = 1400</em>
The area of this rectangle is 1,400m!
<em>1,400 / 56 = 25</em>
So, by multiplying each dimension by 5, the area is now multiplied by 25!
Answer:
18° and 72°
Step-by-step explanation:
Complimentary angles form 90°
We have an angle (x) 4 times larger than the other (y).
Well actually, a system of equations isn't required, so forget about x and y, just divide 90 by 5. This gives you 18, one of the angle's measurements is 18°. Multiply 18 by 4 and get 72. The other angle's measurement is 72°.
