Question

The length and breadth of a rectangle is 18 m. and 12 m. respectively. If the length is increased by 50% and breadth is decreased by 50% then find how much the area is increased / decreased of the new rectangle to the older one.​

Answer 1

Answer:

33

Step-by-step explanation:

Length - 18m

Breadth - 12m

length - 18 + 9 = 27

breadth - 12 - 6 = 6

27 + 6 = 33

Answer 2

Answer:

length of the rectangle 18 m

breadth of the rectangle 12 m

area of the rectangle=18×12 sq m=216 sq m

length is increased by 50%

now length =(18+18×50/100) m=(18+9) m=27 m

breadth is decreased by 50%

now breadth=(12-12×50/100) m=(12-6)m=6m

now area=27×6 sq m=162 sq m

so area decreased by (216-162) sq m=54 sq m
