Answer:
width = 7 and length = 9
Step-by-step explanation:
Let's assume width = w, and length = 2 + w
So area of a rectangle = width * length
63 ft² = w (2 + w)
63 = 2w + w²
w² + 2w - 63 = 0
Use the quadratic formula to solve this
here, a = 1, b = 2 and c = -63
w = 7 or -9
The dimensions of a rectangle cannot be negative. So we take the dimension, w = 7.
Width = 7 and Length = 7+2 = 9
You need 12000 kernals. 1-liter is equal to (10cm)^3. If four kernels fill 1cm^3, it takes 4*1000 kernels to fill one liter. Therefore, to fill a 3-l soft drink bottle, it takes 3*4*1000=12000 kernels.
1/2 * 3 = 1.5 oz of meatloaf
3/4 * 3 = 2.25 oz of mashed potatoes
1/3 * 2 = 0.67 oz of green beans
1.5 + 2.25 + 0.67 = 4.42
