The area of a triangle is 1/2 x base x height.
The base is 2 , the height is 4.
Area = 1/2 x 2 x 4 = 4 square cm.
The area of a square is s^2
S is the length of a side, which is 2
Area = 2^2 = 4 square cm
Both shapes have an area of 4 square cm
Answer: 4.5.
Step-by-step explanation for the triangle:
A = 1/2 ⋅ b ⋅ h A = 1/2 ⋅ 3 ⋅ 3 A= 4.5
OR
Step-by-step explanation for the square:
A = a^2 = 2^2 = 4 = 4.5
