A rectangle has a perimeter of 60 cm. If the length isreduced by 7 cm

1.	A rectangle has a perimeter of 60 cm. If the length isreduced by 7 cm and the breadth is increased by7 cm, the rectangle is made into a square.What are the dimensions of the original rectangle?Length = cmBreadth =cm
Answer» Step-by-step EXPLANATION: Let the original length be l and breadth be b Given:- Perimeter=60 2(l+b)=60 l+b=30_____(1) Now length is REDUCED to 7 and breadth is increased by 7 to make square So l¹=l-7 and b¹=b+7 Since it's a square l¹=b¹ l-7=b+7 l-b=14____(2) (1)+(2)=> l+b+l-b=30+14 2l=44 l=22. Length=22cm (1)-(2)=>l+b-l+b=30-14 2b=16 b=8. Breadth=8cm Hope this answer helped you. please mark my answer as the branliest answer

Step-by-step EXPLANATION:

Let the original length be l and breadth be b

Given:- Perimeter=60

2(l+b)=60

l+b=30_____(1)

Now length is REDUCED to 7 and breadth is increased by 7 to make square

So l¹=l-7 and b¹=b+7

Since it's a square

l¹=b¹

l-7=b+7

l-b=14____(2)

(1)+(2)=> l+b+l-b=30+14

2l=44

l=22. Length=22cm

(1)-(2)=>l+b-l+b=30-14

2b=16

b=8. Breadth=8cm
