Area of triangle = 1/2×base* height

= 1/2 ×12 × 6

= 36 CM²

pErimeter = sum of all sides

=We have to calculate its so by phthogorean formula,,

⏩⏩⏩= √12² + 6²

⏩= √144 +36 =

⏩= 48cm

Peimeter = 48 +12 +6 = 66 cm

Answer 2

Hey Chika ❤

Here's ur answer-

area of ∆ = 1/2 × b × h

area of ∆ = 1/2 × 6 × 12

area of ∆ = 3 × 12

area = 36 cm²

Hence, area of triangle is 36 cm²

perimeter of ∆ = sum of all sides

Given,
b = 6cm
h = 12cm

[triangle here is an isoceles ∆ ]

So, finding the other side - we know that -

h² = b² + p²
h² = (3)² + (12)²
h² = 9 + 144
h² = 153
h² = √153
h² = 12.4
Hence, the other side measures = 12.4 cm

So, perimeter
= 12.4 + 12.4 + 6
=25.4cm

Hope it helps!
