1 answer:
Answer:
a) Perimeter = 10.25 cm
b) Area = 5 cm²
Step-by-step explanation:
a) Perimeter
To find the perimeter we need to add the measure of the three sides of the triangle
P = 2.75 cm + 3.5 cm + 4 cm = 10.25 cm
b) Area
To find the area we need the length of the height and the length of the base.
base = 4 cm
height = 2.5 cm
Formula
Area = base x height /2
Area = 4 x 2.5 / 2 = 5 cm²
