Answer: 87.5
Step-by-step explanation:
The Area formula for a Trapezium is
depicted in the two picture below.
As seen in the picture Area equals
A+B(h) all divided by 1/2 or simplistic terms 2.
A+b
A= ---------- (h)
2
So we need to plug our information in
as Depicted in the picture measurement A is first top side
And B is bottom base
so h IS the height of the figure. Its the middle line in the middle of the figure.
10+15
A= ________(7)
2
10+15=25
25*7=175
175/2=87.5
So your answer is
Area of ABCD is 87.5
Answer: PART A : =
PART B : 5.9 FEET
Step-by-step explanation:
Length of the first sign = 4.4 feet
height of the first sign = 3 feet
Length of the second sign = x feet
height of the second sign = 4 feet
If two shapes are similar , then the ratio of their sides are equal,
That is ;
=
PART A
=
PART B
=
cross multiplying , we have
3x = 4.4 x 4
3x = 17.6
Divide through by 3
x = 17.6/3
x = 5.86666666666667
x≈ 5.9 feet
Therefore , the length of the new sign is 5.9 feet
If A is a subset of B, then all elements from a set A are in a set B.
The number 8 from {3, 8, 6} is not in the set {1, 2, 3, 4, 5, 6}. Therefore {3, 8, 6} is not a subset of {1, 2, 3, 4, 5, 6}.
