Step-by-step explanation:

what is the formula for the area of a triangle ? hmm ?

area = baseline × height / 2

in our case (it does not matter for this question, if it is an isoceles triangle or not, the formula applies to all)

area = sqrt(5) × 1 / 2 = sqrt(5)/2 cm² = 1.118033989... cm²

Answer:

[tex]\huge\boxed{\sf Area = 1.12 \ cm^2}[/tex]

Step-by-step explanation:

Given data:

Height = h = 1 cm

Base = b = √5 cm

Required:

Area = A = ?

Formula:

[tex]\displaystyle Area = \frac{1}{2}(b)(h)[/tex]

Solution:

[tex]\displaystyle Area = \frac{1}{2} (\sqrt{5} )(1)\\\\Area = \frac{\sqrt{5} }{2} \\\\Area = 1.12 \ cm^2\\\\\rule[225]{225}{2}[/tex]
