Question

find the area of an equilateral triangle constructed on the diagonal of a rectangle length and breadth of the rectangle are 5 root 2 cm and 4 root 3 cm respectively​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

(49√3)/2

Step-by-step explanation:

diagonal of rectangle ABCD

(5√2)²+(4√3)² = (AC)²

(AC)² = (50+48)

(AC)² = 98

AC = 7√2

so the side of equilateral trangle will be 7√2.

so area of equilateral trangle

= (√3/4)*(side)²

= (√3/4)*(7√2)²

= (49/2)√3
