Question

5. In a rectangle, if the length is increased by 3 metres and the breadth is decreased by

4 metres,the area of the rectangle is reduced by 67 square metres. If the length is reduced by1m

and the breadth is increased by 4 metres,the area is increased by 89 sq metres. Find

the dimensions of the rectangle.​

Answer 1

Answer: l=28

b=19.

Step-by-step explanation:

the way we solve this problem, is list them equations outta the given question. since we're dealing with area here, remember the formula, A=lxb, and that we use here.

i) (l+4)(b-4)=lb-67

ii)(l-1)(b+4)=lb+89

solve the both equations, you get

4l=112, l=28

2b=38, b=19
