Question

please solve 6 to 10 all​

Answer 1

Answer:

6)1 area = 14,000 cm

6)2 area = 8,800 cm

Step-by-step explanation:

6)1

perimeter = p = 480 cm

length = l = 140 cm

2(l+b) = 480

= 2(140+b) = 480

= 280+2b = 480

= 2b = 480-280

= 2b = 200

= b = 200/2

= b = 100 cm

Therefore, breadth = b = 100 cm

Now, area = lb = 100*140

a = 14,000

6)2

perimeter = p = 1240 cm

breadth = b = 220 cm

= 2(l+b) = 1240

= 2(l+220) = 1240

= 2l+440 = 1240

= 2l =1240-440

= 2l = 800

= l = 400

Therefore, length = l = 400 cm

Now, area = lb = 400*220 = 8800

I will post remaining answers in a while, please be patient.
