Question

1. Side of eqilateral triangle PQR is 8 cm then find the area of triangle whose side is
half of side of triangle PQR​

Answer 1

Answer:

Given : Side of equilateral triangle PQR is 8 cm

To find : the area of triangle whose side is half of side of triangle PQR

Solution:

Area of equilateral triangle = √3 (Side)² / 4

Area of equilateral triangle PQR with side 8 cm

= √3 (8)² / 4

= 16 √3 cm²

area of triangle whose side is half of side of triangle PQR

=> Area = √3 (8/2)² / 4

√3 (4)² / 4

=4 √3 cm²

= (1/4) Area of equilateral trianglePQR

area of triangle whose side is half of side of triangle PQR is (1/4) Area of equilateral triangle PQR

= 4 √3 cm²
