Step-by-step explanation:
Using the section formula, if a point (x,y) divides the line joining the points (x

,y
1
) and (x

,y
2
) in the ratio m:n, then
(x,y)=(

The vertices of the triangle are given to be (x

,y
1
),(x
2
,y
2
) and (x
3
,y

). Let these vertices be A,B and C respectively.
Then the coordinates of the point P that divides AB in l:k will be

Answer:
532m squared is the answer
Step-by-step explanation:
Split the shape into two shapes
one will be a square and the other one a triangle
1) since the length and the width of the square is 18m just Multiply
18x18=324m squared
2) look carefully the width of the square you split is equal to the base of the triangle, so you connect the 18 and the 8 together.
18+8=26m squared
3) Now solve the triangle since you know the height which is 16m squared.
A=lw/2
26x16=416
416 divided by 2 is 208
4) finally just Add
208+324=532m squared
