Question

The area of ​​a rectangle is 21 cm^2 and its perimeter is 20 m. The length breadth of the rectangle and are to be found​

Answer 1

length=7cm and breadth = 3cm

Answer 2

Answer:

L- 7

B-3

Step-by-step explanation:

area = 21 CM ²

perimeter=10 CM

area = l×b

= x× y

21= x×y

. : 7× 3 =21

perimeter= 2(l+ b)

= 2 (x+y)

20 =2(l+ b)

20/2=( l+ b)

10 = ( l + b)

7 + 3 =10 ...

hence L = x = 7

b = y= 3
