Question

The perimeter of a rectangular field is 240 m. If its length is 90 m then its area will be.....

Answer 1

Answer:

perimeter of rectangle=2(l+b)

2(90+b)=240 let breadth be b

180+2b=240

2b= 240-180

2b=60

b=60/2

b= 30

breadth= 30

Answer 2

2700

Step-by-step explanation:

Pimeter of Rectangle=2(L+W)

240 =2(90+W)

240 ÷2 = 90 + W

120 = 90 + W

120-90 = W

30 = W

W = 30

Area of Rectangle = Length × Width

Area = 90 × 30

Area = 2700
