Answer:

a. 15/2 or 7.5 sqcm

b. 20 sqcm

Step-by-step explanation:

Area of a triangle is (base × height)/2.

A = (5×3)/2

A = 15/2 = 7.5cm^2

The area of a parallelogram is just base × height, but yoy have to choose wisely what is the base and height. These two measurements must be perpendicular. So the 4 and 5 are perpendicular. We won't use the measurement 6cm at all.

Area = 4×5

Area = 20 sqcm

All you have to do is line up all of them from least to greatest, then you have to find the middle of all the numbers. the direct middle, like the middle of a number line, with these specific numbers. Hole this helps!
