Question

the perimeter of rectangle floor is 120 M if the length of the floor is 45 M then find out the area of the floor​

Answer 1

Answer:

Step-by-step explanation:

Perimeter of rectangle = 2(l+b)

120= 2l +2b

120= 2×45 +2b

120=90+ 2b

120-90=2b

30= 2b

30/2 = b

b=15

area of rectangle = l×b

                             = 45×15

                             =675m^{2}

Answer 2

Hey mate here's your answer ---

Length = 45 M

let breadth be x

2(X + 45m) = 120 M

x + 45 M = 120/2

X + 45 M =60

X = 60 - 45

X = 15

Area ---

L × B

15 × 45 = $675 M^(2)$
