Question

Perimeter and area of this triangle:

Answer 1

Perimeter =10.25 cm, Area=5 cm^2

Explanation:

Perimeter (for any polygon) can be found adding all the exterior sides together

2.75+4+3.5=10.25

Area for any triangle is the base times the altitude (or line perpendicular to the side/base) divided by 2

4*2.5=10, 10/2=5

Answer 2

Area = 5 cm^2

Primeter = 10.25 cm

Explanation:

The area of triangle is calculated by multiplying height to the base and that divided by two

The height given here is 2.5 cm and base is 4 cm

2.5 × 4 ÷ 2 = 5 cm^2

Primeter of a triangle is calculated by adding side lengths together

a + b + c ➡ 2.75 + 3.5 + 4 = 10.25
