Well first you would start by setting up with a proportion.
In total, the girls paid $54+$22= $76
Thus 1 sister contributed $54/$76=x/100
The other sister contributed $22/$76=x/76
For each proportion, cross-multiply and simplify to get the percentage. The percentage will be the x
Answer is 174 ft2.
Area of triangle: 24 ft2
First, find the horizontal side of the triangle (using pythagorus).
16-10=6
root10^2 - 6^2 = 8 ft
Then work out the area of the triangle.
(8 x 6)/2 = 24 ft2
Secondly, find the area of the rectangle.
10 x 15 = 150 ft2
Then add up the area of the triangle and rectangle.
150+24= 174 ft2

Answer:
x = 11 and 
Step-by-step explanation:
If LMNO is a parallelogram then it's opposite sides will be equal.
So, LM = ON
⇒ 4x + 4 = 5x - 7
⇒ x = 11
Now, MN = OL
⇒ x - 7 = 3y - 4
⇒ 11 - 7 = 3y - 4 {Since we already have, x = 11}
⇒ (Answer)
