Question

the perimeter of a rectangular playground is 256 metres and its length is 74 metres. what it it's area? ​

Answer 1

Answer:

3996m²

Step-by-step explanation:

Length = 74 m

Breadth = x

Perimeter of rectangular playground= 2(l+b)

256 = 2(74+x)

256 = 148 +2x

256-148 = 2x

108 = 2x

108/2 = x

54m = x = breadth.....

now area = l*b

= 74 * 54

= 3996 m²

Answer 2

Answer:

2(l+b) = 256

2(74+b) = 256

74+b= 128

b= 54

Area = l*b

= 74*54

= 3996
