Answer 2

Answer:

(A) 150 cm^2

Step-by-step explanation:

Let breadth be b

then length be 5 + b

Perimeter = 50cm

2(l + b) = 50

2(5 + b + b) = 50

(5 + 2b) =50/2

5 + 2b = 25

2b = 25 - 5

2b = 20

b = 20/2

b = 10

so length = 5 + b = 5 + 10 = 15 cm

breadth = b = 10 cm

Area = l x b = 15 x 10 = 150 cm^2
