Step-by-step explanation:
# Area of painting = 20 × 16
# Area of combination = 25 × 20
.°. Area of frame = Area of combination - Area of painting
= (25×20)-(20×16)
=20 (25-16)
=20 × 9

If you would graph the triangle, one of the legs would be 8 and another would be 5 and the area of a triangle is bxh/2 so the equation is 8x5/2=20un².
Hope this helped! :)
The answer is 5.2π in² = 16.3 in²
The area (A) of the circle with radius r is: A = r²π
It is known:
π = 3.14
t = 5
⇒
A = r²π = (16/7)²π = (2.28)²π = 5.2π = 5.2 · 3.14 = 16.3 in²
It moves in a horizontal line. Its 'y value' does not change.
