3/20x = 9.......with x being the total cost of the food
x = 9 / (3/20)
x = 9 * 20/3
x = 180/3
x = 60 <===
We know that AXB + CYD and AXB + FZE = 90
20 + CYD = 90 and 20 + FZE = 90
We can see that CYD and FZE are equal so we can use one equation
Let's use 20 + CYD = 90
CYD = 70 and FZE is also equal to 70 because CYD and FZE are equal.
so 70 + 70 = 140 degree
Perimeter will be 5+5+4+4=18
Area will be 5*4=20
