240+140+168+96
380+264
644 cm^2
Solution:
We have: In the attached image, observe rectangle triangle ΔBAD
Use the Pythagorean Theorem:
BD = √(AB² + AD²)
BD = √(2² + 4²)
BD = √(4 + 16)
BD = √20
In the attached image, observe rectangle triangle ΔBDH
Use the Pythagorean Theorem:
BH = √(BD² + DH²)
BH = √(√20² + 5²)
BH = √(20 + 25)
BH = √45
BH = √(9 × 5)
BH = √9 × √ 5
BH = 3√5
BH = 3 × 2.24
BH = 6.72 cm

Step-by-step explanation:
Answer:
Answer below
Step-by-step explanation:
Considering the information of the Adult T-shirt sizes, calculate the length of a large size T-shirt. using the small and the medium sizes to check your answer.
a) medium size
30/20 = x/22
x = 30x22/20
x = 660/20
x = 33 in
b) small
27/18 = x/22
x = 22x27/ 18
x = 594/18
x = 33 in
Both results are equal that mean that doesn't matter which measures are used to calcule the sizes of another T-shirt, There is proportion among them.
