Short answer: B
Remark
A 45 degree angle means that the height is the same length as part of the base. But which part?
Givens
b1 = 9 feet
b2 = 23 feet
and the 45 degree angle on the right.
Determine the height.
The part of the base that is associated with the 45 degree angle is found by subtracting b1 from b2
b2 - b1 = 23 - 9 = 14
So 14 is also the height
Find the Area
A = 1/2 (b1 + b2)*h
b1 = 9
b2 = 23
h = 14
Area = 1/2(9 + 23) * 14
Area = 1/2 (32) * 14
Area = 16 * 14
Area = 224 <<<< answer
Answer:
174 1/3
Step-by-step explanation:
314,852
I mean this one is really simple, it just seems hard. So all u have to do is this:
308,328+6,524=314,852
Now subtract to double check
314,852-308,328=6,524.
And yep it’s correct.
I hope this helped, please give brainliest if it helped
2 x (1/2)(11.25)(6) = 67.5
12.75 x 24 = 306
11.25 x 24 = 270
6 x 24 = 144
add all sums together
= 787.5 m^2
Answer: Choice B) 17.5 feet
A = Area of rectangle
L = length
W = width
The formula to use is A = L*W, so we multiply length and width.
We know W = 7 but we don't know what L is.
We know that A = 122.5 is also given
So let's solve for L
A = L*W
L*W = A
L*7 = 122.5 plug in the given values
7*L = 122.5
7*L/7 = 122.5/7 divide both sides by 7
L = 17.5
He should cut 17.5 feet of streamer. Keep in mind that this only applies if Adrian wants to make the streamer completely taut and a straight line across the ceiling/wall. If he wants the streamer to hang down a bit (forming a shape like a rope bridge in a sense), then the streamer's length will have to be a bit longer to account for the extra distance along the curve.
