Answer:
Area - 6 unit^2 Perimeter - 10 units
Step-by-step explanation:
The shaded figure is 3 units long and 2 units high.
L = 3 W = 2
A = LW
A = 3 x 2 = 6 unit^2
Perimeter = 2L + 2W
P = 2(3) + 2(2)
P = 6 + 4 = 10 units

Answer:
The correct option is 1.
Step-by-step explanation:
Given information: AD = 25, CD = 5, DB = 1 and CD⊥AB.
According to the Pythagoras theorem,
![hypotenuse^2=base^2+perpendicular^2](https://tex.z-dn.net/?f=hypotenuse%5E2%3Dbase%5E2%2Bperpendicular%5E2)
In triangle BCD,
![CB^2=DB^2+CD^2](https://tex.z-dn.net/?f=CB%5E2%3DDB%5E2%2BCD%5E2)
![CB^2=1^2+5^2](https://tex.z-dn.net/?f=CB%5E2%3D1%5E2%2B5%5E2)
![CB^2=26](https://tex.z-dn.net/?f=CB%5E2%3D26)
Taking square root both sides.
![CB=\sqrt{26}](https://tex.z-dn.net/?f=CB%3D%5Csqrt%7B26%7D)
In a right angled triangle,
![\sin\theta=\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=%5Csin%5Ctheta%3D%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
![\sin B=\frac{CD}{CB}](https://tex.z-dn.net/?f=%5Csin%20B%3D%5Cfrac%7BCD%7D%7BCB%7D)
![\sin B=\frac{5}{\sqrt{26}}](https://tex.z-dn.net/?f=%5Csin%20B%3D%5Cfrac%7B5%7D%7B%5Csqrt%7B26%7D%7D)
![\sin B=0.980580675691](https://tex.z-dn.net/?f=%5Csin%20B%3D0.980580675691)
![\sin B\approx 0.9806](https://tex.z-dn.net/?f=%5Csin%20B%5Capprox%200.9806)
Therefore the correct option is 1.
