Answer:
Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.
Step-by-step explanation:
Elimination method
Multiply bottom equation by -2. Then combine both
y = -2
Plug into bottom.
x = 6.
Check in top.
12 - 6 = 6
Check in bottom if u want. 6 - 2 = 4
(6,-2)
Let it's width be x
then, it's length = 3x
perimeter of a rectangle = 2 (l+b)
96 = 2 (3x+x)
96 = 8x
12 = x
so the widthe of that rectangle = 12cm and it's length = 3 (12) = 36cm.

Answer:
Area of the frame not covered with photo is equal to 129 square inches
Step-by-step explanation:
Given: Image of a frame
To find: Area of the frame not covered by the picture
Solution:
Area of rectangle = length of the rectangle × breadth of rectangle
Area of the frame = length of frame × breadth of frame = 23 × 15 = 345 square inches
Area of the frame covered with photo = 18 × 12 = 216 square inches
Area of the frame not covered with photo = Area of the frame - Area of the frame covered with photo = 345 - 216 = 129 square inches
