Question

find the area ,perimeter and diagonal of a rectangle ,having ,length =3.2m and breadth=2.4m​

Answer 1

Step-by-step explanation:

area = l × b = 3.2 × 2.4 = 7.68m²

Perimeter = 2(l+b)

= 2(3.2+2.4)

= 2(5.6)

=11.2m

diagonal.of rectangle = √l² +b²

= √10.24 +5.76

=√16

=4m

Answer 2

Answer:

Area = 7.68 m^2

Perimeter = 11.2 m

Diagonal = 4 m

Step-by-step explanation:

Area = length × breadth

= 3.2 × 2.4

= 7.68 m^2

Perimeter = 2( l + b)

= 2 ( 3.2 + 2.4)

= 2 × 5.6

= 11.2 m

Diagonal^2 = length^2 + breadth^2

= (3.2) ^2 + (2.4)^2

= 10.24 + 5.76

= 16

Diagonal = 4 m
