Let the height of the rectangle = h
2b + 2h = 100
2(38) + 2h = 100
2h = 100 - 76
h = 12mm
area of rectangle = base x height
= 38 x 12
= 456mm²
The answer is 10x^2+13x+5
I hope that helped
The answer is 52.
20+52=72
If the radius of the circle is 4 than the area would be 50.27.
If you are saying that 4 is the diameter, than divide that by 2 to get the radius which is 2. The area for this would be 12.57.
I don’t know which one you mean but hope this helps :))
You can find the approximate value of h in this the same way you could with an algebraic expression.
h - 3 < 5
+3
h < 8
