Answer:

It would be 125m^2

Step-by-step explanation:

17*10=170

170/2=85

8*10=80

80/2=40

85+40=125

Answer:

125 square meters

Step-by-step explanation:

Decomposition: Breaking up the shapes, finding their areas individually, and adding up their areas.

Area of a triangle: base * height * 0.5

First, let's look at the area of the top left triangle. The base is 5, while the height is 17. Thus, its area is

5 * 17 * 0.5 = 42.5

The bottom left triangle has a base of 5, and a height of 17, so its area is

5 * 17 * 0.5 = 42.5

The top right triangle has a height of 8 and a base of 5, so its area is

5 * 8 * 0.5 = 20

The bottom right triangle has a height of 8 and base of 5, so its area is

5 * 8 * 0.5 = 20

Now, add up all the areas.

42.5 + 42.5 + 20 + 20 = 125

Thus, the answer is 125 square meters.

I hope this helps! Feel free to ask any questions!

The length of a rectangle is 8 feet more than it’s worth. The area of the rectangle is 84 ft.². Find its Length and width.

Furkat [3]

Answer: 100 i think, but am not sure.

Step-by-step explanation:

The formula for area of a rectangle is A=l*w. Since the area is 84, then you can use the A=l*w formula. 84 = x(x+8) would be the equation to solve for x.

Now, you need to put the equation in standard form. So, x2 + 8x - 84 = 0.

Since you can't solve this quadratic using factoring, you need to complete the square.

To complete the square you need to add 84 to both sides. Now you have x2 + 8x = 84. Take the coefficient for the x term (8) and divide by 2. Now square it. That would be 42, so 16. Now you have x2 +8x +16 = 100.

Factor x2 +8x +16, so (x+4)2 = 100

If you use the square root property, you have x+4 = 10. Therefore, x = 6 (the short side) and 14 is the long side.

W(x) = 2x + 5; Find w(x + 2)

ivolga24 [154]

Solution:

w(x) = 2(x + 2) + 5

w(x) = 2x + 4 + 5

w(x) = 2x + 9

Best of Luck!

Given RT below, if S lies on RT such that the ratio of RS to ST is 3:1, find the coordinates of S.

Ksivusya [100]

Answer:

S(-2, -3)

Step-by-step explanation:

Find the diagram attached below,=. Frim the diagram, the coordinate of R and T are (-5, 3) and (-1, -5) respectively. If the ratio of RS to ST is 3:1, the coordinate of S can be gotten using the midpoint segment formula as shown;

S(X, Y) = {(ax1+bx2/a+b), (ay1+by1/a+b)} where;

x1 = -5, y1 = 3, x2 = -1, y2 = -5, a = 3 and b =1

Substitute the values into the formula;

X = ax2+bx1/a+b

X = 3(-1)+1(-5)/3+1

X = -3-5/4

X = -8/4

X = -2

Similarly;

Y = ay2+by1/a+b

Y = 3(-5)+1(3)/3+1

Y = -15+3/4

Y = -12/4

Y = -3

Hence the coordinate of the point (X, Y) is (-2, -3)
