Question

The perimeter of a rectangular field is 24 m. If its length is 9m, find (i) breadth (ii) area of the rectangle​

Answer 1

• Breadth be x

$\\ \rm\hookrightarrow Perimeter=24$

$\\ \rm\hookrightarrow 2(9+x)=24$

$\\ \rm\hookrightarrow 9+x=12$

$\\ \rm\hookrightarrow x=3$

Now

• Area=Length×Breadth

$\\ \rm\hookrightarrow Area=9(3)=27m^2$

Answer 2

Answer:

breadth: 3 m and area of rectangle: 27 m²

explanation:

part A:

perimeter of rectangle: 2 ( length + breadth )

using the formula:

24 = 2 ( 9 + breadth )

9 + breadth = 12

breadth  = 3 m

part B:

area of the rectangle​ =  length * breadth

using the formula:

9 * 3

27 m²
