Question

3.The perimeter of a Rectangle floor is 120m.If the length of the floor is 45m then find out the area of the floor.

Answer 1

Answer:

breadth = 15m

area = 675m²

Step-by-step explanation:

perimeter of rect. floor = 120 m

2(l+b) = 120m

2(45+b) = 120 m

45+b = 120/2

45+b = 60

b = 60-45

b = 15 m

area of rect. floor = l×b

= 45×15

= 675 m²
