More maths! Will mark brainliest if correct.

Answer:
Step-by-step explanation:
Triangle:
Base = 4 units
Height = 3 units {perpendicular height}
[tex]Area=\frac{1}{2}*base*height\\\\=\frac{1}{2}*4*3\\\\=2*3[/tex]
= 6 square units
Rectangle:
To find the area count the number of squares. Number of square = 6
Area = 6 square units
or You can find the area of the rectangle as bellow also
Length = 3 units
Width = 2 units
Area = length*width
= 3*2
= 6 square units
Both the triangle and rectangles has the same area 6 square units
