Question

Side of an equilateral triangle PQR is 8cm then find the area of triangle whose side is half

of side of triangle PQR.


Give step by step explaination​

Answer 1

Step-by-step explanation:

Given side =8 cm

we know that

area of an equilateral triangle = √3/4 (side)

√3/4(8)²

√3/4(64)

16√3

∴ are of an equilateral triangle =27.712 cm²

Answer 2

Answer:

8cm

Step-by-step explanation:

let the other triangle be ABC

half the side of PQR =4cm.

area of triangle ABC = 1/2 x base x height

= 1/2 x 4 x4

=> 2 x 4 = 8cm
