Answer:
3 . . . goes in both boxes
Step-by-step explanation:
Use the distributive property. Remove the common factor to outside parentheses:
3(m +n) = a multiple of 3
The area of the mat = total area added minus the original area of the water color painting.
length of the mat is:L = 20 in + 1 in + 1 in because 1 in is added to each sideL = 22 inwidth of the mat is:w = 9 in + 1 in + 1inw = 11 in
Area mat = (22 in x 11 in) - ( 20 in x 9 in)
area mat = 62 sq in is the area of the mat
Sin 24 = h/30

Answer:
A= 75.06 Sq Cm
Step-by-step explanation:
Please refer to the picture attached with this.
In ΔABD
AB = 8.5 , AD = 6 and say BD = x
Applying Pythagoras theorem in this triangle
Pythagoras theorem says

where c is the side opposite to the right angle, and b and a are the other two sides of the right angled triangle.




Hence side 
a = 6.02+19
a = 25.02
Now we apply the formula for area of a triangle which is given as

Where b is the base , here we have base as a = 25.02
h is the height , here h = 6
Putting these values in Formula we get



Hence Area of the triangle is 75.06 sq cm
