25*11 is 275 + 170 is 435.
Answer:
67,500 m²
Step-by-step explanation:
ASSUMING the fields look like this __________________
| | |
| | | W
|_________|_________|
L
Let L be the length of the combined field and W be the width
2L + 3W = 1800
2L = 1800 - 3W
L = 900 - 1.5W
A = LW
A = (900 - 1.5W)W
A = 900W - 1.5W²
Area will be maximized when the derivative equals zero.
dA/dW = 900 - 3W
0 = 900 - 3W
3W = 900
W = 300 m
L = 900 - 1.5(300)
L = 450 m
A = LW = 450(300) = 135,000 m²
so each sub field is 135000/2 = 67,500 m²
He spent 1/4 on Monday, so he had 3/4 left.
He then spent 2/3 of that, to find how much he spent you would multiply 3/4 by 2/3:
3/4 x 2/3 = 6/12 = 1/2
On Tuesday he spent 1/2 of his allowance.
So on Monday and Tuesday he spent 1/4 + 1/2 = 3/4 total.
He would have 1/4 of his allowance left.
The answer is C.
