Which figure encloses more area: a square of side 2cm, a rectangle of side 3cm and 2cm or a right triangle of side 4cm.

Answer:

Equilateral Triangle

Step-by-step explanation:

Area of a square = a2

= (2 x 2) cm2

= 4 cm2

Area of rectangle = L X B

= (3 x 2 ) cm2

= 6 cm2

Area of an equilateral triangle = root 3/4 .a2

= root 3/4 .(4)2

= 1.732 / 4 . 16

= 0.433 . 16

= 6.928 cm2

Since the area of an equilateral triangle is more than area of a square and rectangle

So equilateral triangle encloses more area
