Question

If the breadth of a rectangle is 8 cm and length is 15 cm then find it's area and perimeter​

Answer 1

Step-by-step explanation:

length of rectangle=15cm

breadth of rectangle=8cm

we know that

perimeter of rectangle=2(l+b)

=2(15+8)

=2×23

=46cm

hence,perimeter of rectangle is 46cm.

therefore,area of rectangle=l×b

=15×8

=120cm^2

hence,area of rectangle is 120cm^2

Answer 2

Given ;

Breadth (b) = 8 cm

Length (l) = 15 cm

Perimeter of a rectangle :

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \large \boxed{2(l + b)}$

Area of a rectangle:

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \large \boxed{l \times b}$

Substituting the given values ;

Perimeter :

$2(15 + 8) \\ 2(23) \\ 46$

Perimeter of the rectangle = 46 cm

Area :

$(15 \times 8) \\ 120$

Area of the rectangle = 120 sq. cm
