Hope this helps
Okay......................
Have a good day!
Another way to do it is
2x-y=17
x-y=10, x=10+y
substitute x=10+y for x in 2x-y=17 and get
2(10+y)-y=17
20+2y-y=17
20+y=17
subtract 20 from both sides
y=-3
subsitute y=-3 into equation x-y=10
x-(-3)=10
x+3=10
subtract 3 from both sides
x=7
or subsitute into 2x-y=17
2x-(-3)=17
2x+3=17
subtract 3 from both sides
2x=14
divide both sides by two
x=7
Area = 32 units^2. Formula for a right angle triangle is Length x Width x 1/2. The biggest triangle is 4 x 10. Put that into the formula you get 4 x 10 x 1/2 which equals 20. Medium triangle is 2 x 6. In the formula it’s 2 x 6 x 1/2 = 6. Small triangle is 2 x 2. In the formula it’s 2 x 2 x 1/2 = 2. And the small square is 2 x 2 which you multiply normally to equal 4. Now add them all up to get 32 units^2
