Question

36. Area of a rectangular ground is
12500m'. Its length is 125 m.
Its perimeter is

a. 450m
b. 100m
c. 900m
d. 1250m​

Answer 1

Answer:

a) 450 m

Step-by-step explanation:

Area of rectangle = L × B

12500 = 125 × B

100 = B

We know that ,

Perimeter of rectangle= 2( L + B )

= 2 ( 125 + 100 )

= 2 × 225

= 450

Opt. a) 450 metres is the answer.

Answer 2

» Area of a rectangular ground is

12500 m.

We know that area of rectangle = l × b

Here..

• l = length

• b = breadth

length (l) = 125 m ______ [GIVEN]

We have to find it's perimeter.

Before finding it's perimeter. We have to find it's bread first.

_____________________________

Now..

Area of rectangle = l × b

=> 12500 = 125 × b

=> b = $\dfrac{12500}{125}$

=> b = 100 m

____________________________

Perimeter of rectangle = 2(l + b)

=> 2(125 + 100)

=> 2 × 225

=> 450 m

___________________________

Perimeter of rectangle is 450 m

Option a)
