Figure ABCD - Figure EFGH

Colt1911 [192]

<h3>Answer:</h3>

30.5 units

<h3>Step-by-step explanation:</h3>

We know that:

Trapezoid ABCD has one side that is 25 unit.
The other 3 sides (AB, BC, and CD) are 12 units.
EF = 6 units
EH = 12.5
Trapezoid ABCD is congruent to Trapezoid EFGH

If the 3 sides of the trapezoid ABCD are the same sides, then side EF, FG, GH must be of the same length because of congruence. The value of FG and GH must be the same length as EF. We can clearly see in the picture that EF is 6 units. Hence, EF is 6 units, FG is 6 units, and GH is 6 units. The work of the perimeter is shown below.

Work

=> 6(3) + 12.5
=> 18 + 12.5
=> 30.5 units

Hence, the perimeter of EFGH is 30.5 units.

Pls help me with this math

Alexeev081 [22]

Answer:

62 is your answer

Step-by-step explanation:

6 × (36 ÷ 12)² + 8, you can also write 36 ÷ 12 as a fraction, which would look like this: 36/12

Step 1: 6 × 36/12² + 8 = 6 × 3² + 8

Step 2: Multiply 6 and 9

(6)(9)+8 = 54+8

Step 3: Then you add 54 and 9 and you get 62

Answer: 62
