Question

Mathematics
height=1cm,base=√5cm.what is the area of isosceles triangle?

Answer 1

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 2

`\huge\boxed{\sf Area = 1.12 \ cm^2}`

Explanation:

Given data:

Height = h = 1 cm

Base = b = √5 cm

Required:

Area = A = ?

Formula:

`\displaystyle Area = (1)/(2)(b)(h)`

Solution:

`\displaystyle Area = (1)/(2) (√(5) )(1)\\\\Area = (√(5) )/(2) \\\\Area = 1.12 \ cm^2\\\\\rule[225]{225}{2}`
