The trapezoid's area is 126 inch².
Step-by-step explanation:
Step 1:
The trapezoid's area is calculated by averaging the base lengths and multiplying it with the trapezoid's height.
The trapezoid's area,
.
Here
is the lower base and
is the upper base, height is h.
Step 2:
In the given diagram,
inches and
inches and h = 9 inches.
inch².
So the given trapezoid's area is 126 inch².
Answer:
32 plz give brainiest
Step-by-step explanation:
I'd start by recognizing that the smaller triangle, at the top, is similar to the larger (whole) triangle.
Then:
a b
------- = ---------
15+a 20+b
Then 20a + ab = 15b + ab. Subtract ab from both sides. We then get 20a = 15b. Note also that
40 b
----- = ----------
60 b+20
so that 40b + 800 = 60b, or 800 = 20b, or b = 40.
If b = 40, then we can find a from the relationship 20a = 15b found earlier. With b=40, 20a = 15(40) = 600, so a = 30
a = 30
b= 40
Answer:
$13,795
Step-by-step explanation:
15500/x=100/11
(15500/x)*x=(100/11)*x - we multiply both sides of the equation by x
15500=9.0909090909091*x - we divide both sides of the equation by (9.0909090909091) to get x
15500/9.0909090909091=x
1705=x
x=1705
now we have:
11% of 15500=1705
