Question

2. The area of a rectangle is 120 m². If its breadth is 12 m, then its perimeter is_
​

Answer 1

Answer:

44m

Step-by-step explanation:

first use the formula of area to find the length

l×b =area

l×12 =120

l = 120/12

l = 10

As we have both the length and breath of a rectangle we can find the perimeter

2×(l+b) = perimeter

2 × (10 + 12) = perimeter

2× 22 = perimeter

44 m = perimeter

Hope it helps you!!

Answer 2

Answer:

Perimeter of rectangle = 44 m

Step-by-step explanation:

Area of rectangle = l × b = 120 m.sq

breadth = 12 m

let us take length as x

then x × 12 = 120

therefore x = 120 ÷ 12

= 10

length of rectangle = 10 m

Perimeter of rectangle = 2( l + b )

= 2 ( 10 + 12 )

= 44 m
