Answer:</h2>
<h2>
Step-by-step explanation:</h2>
A rectangle is a quadrilateral whose angles are all right angles. In this problem, we have a rectangle whose height and whose area is . We don't know the other side of the rectangle, but let's call it . So the area of a rectangle is:
The perimeter is the distance around a shape in two dimensions. For our rectangle, our perimeter is:
So our goal is to find . From the equation of the area:
If we substitute both this value and the height in the equation of the perimeter we get:
The answer is
2)40
3)y=3\2
I think it is b not 100% tho
Answer:
The answer is 314cm²
the formula for the sphere area of a sphere is:
A= 4TT²
A = 4x3.14x5²
first solve for exponents
A = 4x 3.14x25
then multiply
A = 314cm²
