Question

If the perimeter of a retangular field is 200m and its breadth is 40m find its area in m2

Answer 1

Answer:

Step-by-step explanation:Given: perimeter = 200 m

Breadth = 40 m

Perimeter = 2 (l+b)

P = 2(l+40)

200=2 (l+40)

200=(2×l)+(2×40)

200=2l+80

2l=200-80=120

2l=120

l=120÷2

60 m

Area = l×b=2400m2
