A.T.Q, equations will be:
x+y = 450
2x+5y= 1800
Substitute value of x from equation (1), in equation (2)
2(450-y) +5y=1800
900-2y+5y=1800
3y=900
y=300
so, your answer is 300

We have to calculate the length of a side ( x ) of the rectangle. We know the perimeter of the rectangle: P = 24 ft. Formula for the perimeter of the rectangle is: P = 2 L + 2 W. The width W = 4 ft. So: 24 = 2 * x + 2 * 4; 24 = 2 * x + 8; 2 * x = 24 - 8; 2 * x = 16; x = 16 : 2; x = 8. Answer: The length of side of a rectangle is 8 feet<span>.</span>
